Iran criticized a U.S. move to deploy low-yield nuclear missiles on submarines, saying at a disarmament conference on Tuesday it made nuclear war "more likely".
The U.S. Defense Department said earlier this month the Navy had fielded a low-yield, submarine-launched ballistic missile warhead, something the Pentagon says is needed to deter adversaries like Russia. Moscow has already expressed alarm at the decision.
"Such provocative actions must be condemned," Mohsen Baharvand, Iran's deputy foreign minister for international and legal affairs, told the Conference on Disarmament in the UN building in Geneva.
