GENEVA (AP) — More than 100 nations concluding a round of global nuclear talks Friday expressed alarm that many nuclear weapons are kept at a high-alert level and are still being modernized, despite a promise to get rid of them.

The statement was, in effect, a complaint about — and by — some of the most powerful members of the Nuclear Non-Proliferation Treaty, since the U.S. and Russia were included in it. They are known to possess most of the world’s hundreds of launch-ready ballistic missiles that can be ordered to quickly deliver their payload, a nuclear warhead.
