Russian Calls for New Chemical Weapons Accord

GENEVA — Russia’s foreign minister called on Tuesday for negotiations on a new international treaty to counter the “extremely urgent” threat of chemical warfare by terrorists, as exemplified by attacks by Islamic State forces in Syria and Iraq last year.

“Chemical terrorism is emerging not as an abstract threat but a grave reality of our time,” the minister, Sergey V. Lavrov, told diplomats attending United Nations-sponsored Conference on Disarmament talks in Geneva.
