Chad Ratifies Test Ban Treaty

Chad on Friday became the 159th nation to ratify the Comprehensive Test Ban Treaty.

The move came nearly 17 years after the African state signed the accord against trial detonations that are key to building a nuclear arsenal.

The treaty cannot enter into force until it receives legislative approval from 44 "Annex 2" nations that operated atomic energy or research reactors while participating in CTBT negotiations during the 1990s. The holdouts in that group are China, Egypt, India, Iran, Israel, North Korea, Pakistan and the United States.
