Israel's envoy to the United Nations, Danny Danon, told the Security Council on Friday his country would not stop its attacks "until Iran's nuclear threat is dismantled". Iran's U.N. envoy Amir Saeid Iravani called for Security Council action and said Tehran was alarmed by reports that the U.S. might join the war.

Iran and Israel exchanged fresh attacks in the early hours of Saturday, escalating an already tense conflict as diplomatic efforts to revive nuclear talks floundered and Europe scrambled to keep dialogue alive.
