INTERNATIONAL CONVENTION FOR THE SUPPRESSION OF ACTS OF

NUCLEAR TERRORISM

International Convention for the Suppression of Acts of Nuclear Terrorism

The States Parties to this Convention,

Having in mind the purposes and principles of the Charter of the United Nations

concerning the maintenance of international peace and security and the promotion of

good-neighbourliness and friendly relations and cooperation among States,

Recalling the Declaration on the Occasion of the Fiftieth Anniversary of the United

Nations of 24 October 1995,

Recognizing the right of all States to develop and apply nuclear energy for peaceful

purposes and their legitimate interests in the potential benefits to be derived from the

peaceful application of nuclear energy,

Bearing in mind the Convention on the Physical Protection of Nuclear Material of

19801,

Deeply concerned about the worldwide escalation of acts of terrorism in all its forms

and manifestations,

Recalling the Declaration on Measures to Eliminate International Terrorism annexed to

General Assembly resolution 49/60 of 9 December 1994, in which, inter alia, the

States Members of the United Nations solemnly reaffirm their unequivocal

condemnation of all acts, methods and practices of terrorism as criminal and

unjustifiable, wherever and by whomever committed, including those which jeopardize

the friendly relations among States and peoples and threaten the territorial integrity and

security of States,

Noting that the Declaration also encouraged States to review urgently the scope of the

existing international legal provisions on the prevention, repression and elimination of

terrorism in all its forms and manifestations, with the aim of ensuring that there is a

comprehensive legal framework covering all aspects of the matter,

Recalling General Assembly resolution 51/210 of 17 December 1996 and the

Declaration to Supplement the 1994 Declaration on Measures to Eliminate

International Terrorism annexed thereto,

Recalling also that, pursuant to General Assembly resolution 51/210, an ad hoc

committee was established to elaborate, inter alia, an international convention for the

1 Treaty Series No.061 (1995) Cm 2945

4

suppression of acts of nuclear terrorism to supplement related existing international

instruments,

Noting that acts of nuclear terrorism may result in the gravest consequences and may

pose a threat to international peace and security,

Noting also that existing multilateral legal provisions do not adequately address those

attacks,

Being convinced of the urgent need to enhance international cooperation between

States in devising and adopting effective and practical measures for the prevention of

such acts of terrorism and for the prosecution and punishment of their perpetrators,

Noting that the activities of military forces of States are governed by rules of

international law outside of the framework of this Convention and that the exclusion of

certain actions from the coverage of this Convention does not condone or make lawful

otherwise unlawful acts, or preclude prosecution under other laws,

Have agreed as follows:

ARTICLE 1

For the purposes of this Convention:

1. “Radioactive material” means nuclear material and other radioactive substances

which contain nuclides which undergo spontaneous disintegration (a process

accompanied by emission of one or more types of ionizing radiation, such as alpha-,

beta-, neutron particles and gamma rays) and which may, owing to their radiological or

fissile properties, cause death, serious bodily injury or substantial damage to property

or to the environment.

2. “Nuclear material” means plutonium, except that with isotopic concentration

exceeding 80 per cent in plutonium-238; uranium-233; uranium enriched in the isotope

235 or 233; uranium containing the mixture of isotopes as occurring in nature other

than in the form of ore or ore residue; or any material containing one or more of the

foregoing;

Whereby “uranium enriched in the isotope 235 or 233” means uranium containing the

isotope 235 or 233 or both in an amount such that the abundance ratio of the sum of

these isotopes to the isotope 238 is greater than the ratio of the isotope 235 to the

isotope 238 occurring in nature.

3. “Nuclear facility” means:

5

(a) Any nuclear reactor, including reactors installed on vessels, vehicles,

aircraft or space objects for use as an energy source in order to propel

such vessels, vehicles, aircraft or space objects or for any other purpose;

(b) Any plant or conveyance being used for the production, storage,

processing or transport of radioactive material.

4. “Device” means:

(a) Any nuclear explosive device; or

(b) Any radioactive material dispersal or radiation-emitting device which may,

owing to its radiological properties, cause death, serious bodily injury or

substantial damage to property or to the environment.

conveyance that is used or occupied by representatives of a State, members of a

Government, the legislature or the judiciary or by officials or employees of a State or

any other public authority or entity or by employees or officials of an

intergovernmental organization in connection with their official duties.

organized, trained and equipped under its internal law for the primary purpose of

national defence or security and persons acting in support of those armed forces who

are under their formal command, control and responsibility.

understood under international humanitarian law, which are governed by that law are

not governed by this Convention, and the activities undertaken by military forces of a

State in the exercise of their official duties, inasmuch as they are governed by other

rules of international law, are not governed by this Convention.

racial, ethnic, religious or other similar nature and are punished by penalties consistent

with their grave nature.

8

ARTICLE 7

1. States Parties shall cooperate by:

(a) Taking all practicable measures, including, if necessary, adapting their

information which they are not permitted to communicate pursuant to national law or

which would jeopardize the security of the State concerned or the physical protection

of nuclear material.

4. States Parties shall inform the Secretary-General of the United Nations of their

competent authorities and liaison points responsible for sending and receiving the

information referred to in the present article. The Secretary- General of the United

Nations shall communicate such information regarding competent authorities and

liaison points to all States Parties and the International Atomic Energy Agency. Such

authorities and liaison points must be accessible on a continuous basis.

9

ARTICLE 8

For purposes of preventing offences under this Convention, States Parties shall make

every effort to adopt appropriate measures to ensure the protection of radioactive

material, taking into account relevant recommendations and functions of the

International Atomic Energy Agency.

ARTICLE 9

1. Each State Party shall take such measures as may be necessary to establish its

jurisdiction over the offences set forth in article 2 when:

(a) The offence is committed in the territory of that State; or

(b) The offence is committed on board a vessel flying the flag of that State or

an aircraft which is registered under the laws of that State at the time the

establish its jurisdiction over the offences set forth in article 2 in cases where the

alleged offender is present in its territory and it does not extradite that person to any of

the States Parties which have established their jurisdiction in accordance with

paragraph 1 or 2 of the present article.

5. This Convention does not exclude the exercise of any criminal jurisdiction

established by a State Party in accordance with its national law.

ARTICLE 10

1. Upon receiving information that an offence set forth in article 2 has been

committed or is being committed in the territory of a State Party or that a person who

has committed or who is alleged to have committed such an offence may be present in

its territory, the State Party concerned shall take such measures as may be necessary

under its national law to investigate the facts contained in the information.

2. Upon being satisfied that the circumstances so warrant, the State Party in whose

territory the offender or alleged offender is present shall take the appropriate measures

under its national law so as to ensure that person’s presence for the purpose of

prosecution or extradition.

3. Any person regarding whom the measures referred to in paragraph 2 of the

present article are being taken shall be entitled:

(a) To communicate without delay with the nearest appropriate representative

of the State of which that person is a national or which is otherwise entitled

to protect that person’s rights or, if that person is a stateless person, the

State in the territory of which that person habitually resides;

(b) To be visited by a representative of that State;

(c) To be informed of that person’s rights under subparagraphs (a)

and (b).

4. The rights referred to in paragraph 3 of the present article shall be exercised in

conformity with the laws and regulations of the State in the territory of which the

regulations must enable full effect to be given to the purposes for which the rights

accorded under paragraph 3 are intended.

custody, it shall immediately notify, directly or through the Secretary- General of the

United Nations, the States Parties which have established jurisdiction in accordance

with article 9, paragraphs 1 and 2, and, if it considers it advisable, any other interested

States Parties, of the fact that that person is in custody and of the circumstances which

warrant that person’s detention. The State which makes the investigation contemplated

in paragraph 1 of the present article shall promptly inform the said States Parties of its

findings and shall indicate whether it intends to exercise jurisdiction.

ARTICLE 11

1. The State Party in the territory of which the alleged offender is present shall, in

cases to which article 9 applies, if it does not extradite that person, be obliged, without

exception whatsoever and whether or not the offence was committed in its territory, to

submit the case without undue delay to its competent authorities for the purpose of

prosecution, through proceedings in accordance with the laws of that State. Those

authorities shall take their decision in the same manner as in the case of any other

offence of a grave nature under the law of that State.

2. Whenever a State Party is permitted under its national law to extradite or

otherwise surrender one of its nationals only upon the condition that the person will be

returned to that State to serve the sentence imposed as a result of the trial or

proceeding for which the extradition or surrender of the person was sought, and this

State and the State seeking the extradition of the person agree with this option and

other terms they may deem appropriate, such a conditional extradition or surrender

shall be sufficient to discharge the obligation set forth in paragraph 1 of the present

article.

ARTICLE 12

Any person who is taken into custody or regarding whom any other measures are taken

or proceedings are carried out pursuant to this Convention shall be guaranteed fair

treatment, including enjoyment of all rights and guarantees in conformity with the law

of the State in the territory of which that person is present and applicable provisions of

international law, including international law of human rights.

12

ARTICLE 13

1. The offences set forth in article 2 shall be deemed to be included as extraditable

offences in any extradition treaty existing between any of the States Parties before the

entry into force of this Convention. States Parties undertake to include such offences as

extraditable offences in every extradition treaty to be subsequently concluded between

them.

2. When a State Party which makes extradition conditional on the existence of a

treaty receives a request for extradition from another State Party with which it has no

extradition treaty, the requested State Party may, at its option, consider this

Convention as a legal basis for extradition in respect of the offences set forth in article

2. Extradition shall be subject to the other conditions provided by the law of the

requested State.

3. States Parties which do not make extradition conditional on the existence of a

treaty shall recognize the offences set forth in article 2 as extraditable offences

between themselves, subject to the conditions provided by the law of the requested

State.

4. If necessary, the offences set forth in article 2 shall be treated, for the purposes of

extradition between States Parties, as if they had been committed not only in the place

in which they occurred but also in the territory of the States that have established

jurisdiction in accordance with article 9, paragraphs 1 and 2.

5. The provisions of all extradition treaties and arrangements between States Parties

with regard to offences set forth in article 2 shall be deemed to be modified as between

States Parties to the extent that they are incompatible with this Convention.

ARTICLE 14

1. States Parties shall afford one another the greatest measure of assistance in

connection with investigations or criminal or extradition proceedings brought in

respect of the offences set forth in article 2, including assistance in obtaining evidence

at their disposal necessary for the proceedings.

2. States Parties shall carry out their obligations under paragraph 1 of the present

article in conformity with any treaties or other arrangements on mutual legal assistance

that may exist between them. In the absence of such treaties or arrangements, States

Parties shall afford one another assistance in accordance with their national law.

13

ARTICLE 15

None of the offences set forth in article 2 shall be regarded, for the purposes of

extradition or mutual legal assistance, as a political offence or as an offence connected

with a political offence or as an offence inspired by political motives. Accordingly, a

request for extradition or for mutual legal assistance based on such an offence may not

be refused on the sole ground that it concerns a political offence or an offence

connected with a political offence or an offence inspired by political motives.

ARTICLE 16

Nothing in this Convention shall be interpreted as imposing an obligation to extradite

or to afford mutual legal assistance if the requested State Party has substantial grounds

for believing that the request for extradition for offences set forth in article 2 or for

mutual legal assistance with respect to such offences has been made for the purpose of

prosecuting or punishing a person on account of that person’s race, religion,

nationality, ethnic origin or political opinion or that compliance with the request would

cause prejudice to that person’s position for any of these reasons.

ARTICLE 17

1. A person who is being detained or is serving a sentence in the territory of one

State Party whose presence in another State Party is requested for purposes of

testimony, identification or otherwise providing assistance in obtaining evidence for

the investigation or prosecution of offences under this Convention may be transferred

(b) The competent authorities of both States agree, subject to such conditions

as those States may deem appropriate.

its obligation to return the person to the custody of the State from which

the person was transferred as agreed beforehand, or as otherwise agreed,

by the competent authorities of both States;

14

(c) The State to which the person is transferred shall not require the State from

which the person was transferred to initiate extradition proceedings for the

return of the person;

(d) The person transferred shall receive credit for service of the sentence being

served in the State from which he or she was transferred for time spent in

the custody of the State to which he or she was transferred.

3. Unless the State Party from which a person is to be transferred in accordance

with the present article so agrees, that person, whatever his or her nationality, shall not

be prosecuted or detained or subjected to any other restriction of his or her personal

liberty in the territory of the State to which that person is transferred in respect of acts

or convictions anterior to his or her departure from the territory of the State from

which such person was transferred.

modalities of return and storage) with the States Parties concerned to the State Party to

which it belongs, to the State Party of which the natural or legal person owning such

radioactive material, device or facility is a national or resident, or to the State Party

from whose territory it was stolen or otherwise unlawfully obtained.

3. (a) Where a State Party is prohibited by national or international law from

returning or accepting such radioactive material, device or nuclear facility

or where the States Parties concerned so agree, subject to paragraph 3 (b)

of the present article, the State Party in possession of the radioactive

material, devices or nuclear facilities shall continue to take the steps

15

described in paragraph 1 of the present article; such radioactive material,

devices or nuclear facilities shall be used only for peaceful purposes;

(b) Where it is not lawful for the State Party in possession of the radioactive

material, devices or nuclear facilities to possess them, that State shall

ensure that they are placed as soon as possible in the possession of a State

for which such possession is lawful and which, where appropriate, has

provided assurances consistent with the requirements of paragraph 1 of the

present article in consultation with that State, for the purpose of rendering

it harmless; such radioactive material, devices or nuclear facilities shall be

used only for peaceful purposes.

material, device or nuclear facility pursuant to the present article shall inform the

Director General of the International Atomic Energy Agency of the manner in which

such an item was disposed of or retained. The Director General of the International

Atomic Energy Agency shal l transmit the information to the other States Parties.

7. In the event of any dissemination in connection with an offence set forth in

article 2, nothing in the present article shall affect in any way the rules of international

law governing liability for nuclear damage, or other rules of international law.

ARTICLE 19

The State Party where the alleged offender is prosecuted shall, in accordance with its

national law or applicable procedures, communicate the final outcome of the

proceedings to the Secretary-General of the United Nations, who shall transmit the
