Senior government officials will press for the early entry into force of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) when they meet on 27 September at UN Headquarters in New York, where the treaty first opened for signature 16 years ago, Un reports. The CTBT is the only treaty to ban all nuclear tests, everywhere and by everyone. The treaty also has a unique global alarm system to detect nuclear explosions.

With the combination of the treaty and its verification system, the international community has “virtually pushed the genie of nuclear explosions back in the bottle,” the Executive Secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), Tibor Tóth, said .
The CTBTO is tasked with building up the treaty’s verification regime so that it is fully operational when the treaty enters into force, and with promoting signatures and ratifications.
