UNITED NATIONS (AP) — The first-ever treaty to ban nuclear weapons entered into force on Friday, hailed as a historic step to rid the world of its deadliest weapons but strongly opposed by the world’s nuclear-armed nations.
The Treaty on the Prohibition of Nuclear Weapons is now part of international law, culminating a decades-long campaign aimed at preventing a repetition of the U.S. atomic bombings of Hiroshima and Nagasaki at the end of World War II.
