Djibouti ratifies Comprehensive
Nuclear-Test-Ban Treaty

Djibouti has deposited its instrument of ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) with the United Nations Secretary-General on 15 July 2005, bringing the total number of ratifications to 122. The number of ratifying States in the Africa geographical region now stands at 28.

Djibouti hosts two International Monitoring System (IMS) facilities; an auxiliary seismic station at Arta Tunnel and an infrasound station at Djibouti. The two stations form part of the global network of 337 IMS monitoring facilities being established under the terms of the CTBT to verify compliance with the terms of the Treaty. The monitoring facilities transmit data via satellite to the International Data Centre (IDC) in Vienna, where the data are used to detect, locate and characterize events. These data and IDC products are made available to the States Signatories for final analysis.

The CTBT bans all nuclear weapons test explosions. Drafted at the Conference on Disarmament in Geneva, and adopted by the General Assembly on 10 September 1996, the Treaty was opened for signature on 24 September 1996 at the Untied Nations headquarters in New York.

To enter into force, the CTBT must be singed and ratified by the 44 States listed in Annex 2 to the Treaty. These States formally participated in the work of the 1996 session of the Conference on Disarmament and possessed nuclear power or research reactors at that time. To date, 33 of the Annex 2 States have ratified the Treaty.
