RECOGNIZING in particular that everyone has the right to life, liberty and security of person, as set out in the Universal Declaration of Human Rights and the International Covenant on Civil and Political Rights,

REAFFIRMING the principle of equal rights and self-determination of peoples as enshrined in the Charter of the United Nations and the Declaration on Principles of International Law concerning Friendly Relations and Co-operation among States in accordance with the Charter of the United Nations, as well as in other relevant resolutions of the General Assembly,

CONSIDERING that the taking of hostages is an offence of grave concern to the international community and that, in accordance with the provisions of this Convention, any person committing an act of hostage taking shall either be prosecuted or extradited,

BEING CONVINCED that it is urgently necessary to develop international co-operation between States in devising and adopting effective measures for the prevention, prosecution and punishment of all acts of taking of hostages as manifestations of international terrorism,

Have agreed as follows:

Any person who seizes or detains and threatens to kill, to injure or to continue to detain another person (hereinafter referred to as the “hostage”) in order to compel a third party, namely, a State, an international intergovernmental organization, a natural or juridical person, or a group of persons, to do or abstain from doing any act as an explicit or implicit condition for the release of the hostage commits the offence of taking of hostages (“hostage-taking”) within the meaning of this Convention.

2. Any person who:

(a)  Attempts to commit an act of hostage-taking, or

(b)  Participates as an accomplice of anyone who commits or attempts to commit an act of hostage-taking

If any object which the offender has obtained as a result of the taking of hostages comes into the custody of a State Party, that State Party shall return it as soon as possible to the hostage or the third party referred to in article 1, as the case may be, or to the appropriate authorities thereof.

Article 4

3. This Convention does not exclude any criminal jurisdiction exercised in accordance with internal law.

Article 6

1. Upon being satisfied that the circumstances so warrant, any State Party in the territory of which the alleged offender is present shall, in accordance with its laws, take him into custody or take other measures to ensure his presence for such time as is necessary to enable any criminal or extradition proceedings to be instituted.

4. The rights referred to in paragraph 3 of this article shall be exercised in conformity with the laws and regulations of the State in the territory of which the alleged offender is present subject to the proviso, however, that the said laws and regulations must enable full effect to be given to the purposes for which the rights accorded under paragraph 3 of this article are intended.

5. The provisions of paragraphs 3 and 4 of this article shall be without prejudice to the right of any State Party having a claim to jurisdiction in accordance with paragraph 1(b) of article 5 to invite the International Committee of the Red Cross to communicate with and visit the alleged offender.

6. The State which makes the preliminary inquiry contemplated in paragraph 1 of this article shall promptly report its findings to the States or organization referred to in paragraph 2 of this article and indicate whether it intends to exercise jurisdiction.

Article 8

1. The State Party in the territory of which the alleged offender is found shall, if it does not extradite him, be obliged, without exception whatsoever and whether or not the offence was committed in its territory, to submit the case to its competent authorities for the purpose of prosecution, through proceedings in accordance with the laws of that State.

1. A request for the extradition of an alleged offender, pursuant to this Convention, shall not be granted if the requested State Party has substantial grounds for believing:

(a) That the request for extradition for an offence set forth in article 1 has been made for the purpose of prosecuting or punishing a person on account of his race, religion, nationality, ethnic origin or political opinion; or

(b) That the person’s position may be prejudiced:

(i) for any of the reasons mentioned in subparagraph (a) of this paragraph, or

(ii) for the reason that communication with him by the appropriate authorities of the State entitled to exercise rights of protection cannot be effected.

2. With respect to the offences as defined in this Convention, the provisions of all extradition treaties and arrangements applicable between States Parties are modified as between States Parties to the extent that they are incompatible with this Convention.

1. States Parties shall afford one another the greatest measure of assistance in connexion with criminal proceedings brought in respect of the offences set forth in article 1, including the supply of all evidence at their disposal necessary for the proceedings.

2. The provisions of paragraph 1 of this article shall not affect obligations concerning mutual judicial assistance embodied in any other treaty.

Article 12

In so far as the Geneva Conventions of 1949 for the protection of war victims¹ or the Protocols Additional to those Conventions² are applicable to a particular act of hostage-taking, and in so far as States Parties to this Convention are bound under those conventions to prosecute or hand over the hostage-taker, the present Convention shall not apply to an act of hostage-taking committed in the course of armed conflicts as defined in the Geneva Conventions of 1949 and the Protocols thereto, including armed conflicts mentioned in article 1, paragraph 4, of Additional Protocol I of 1977, in which peoples are fighting against colonial domination and alien occupation and against racist régimes in the exercise of their right of self-determination, as enshrined in the Charter of the United Nations and the Declaration on Principles of International Law concerning Friendly Relations and Co-operation among States in accordance with the Charter of the United Nations.

Article 13

This Convention shall not apply where the offence is committed within a single State, the hostage and the alleged offender are nationals of that State and the alleged offender is found in the territory of that State.

Article 14

Nothing in this Convention shall be construed as justifying the violation of the territorial integrity or political independence of a State in contravention of the Charter of the United Nations.
