The U.S. and Western allies clashed with Russia and China on Thursday over Iran¡¯s nuclear intentions, as Washington sought, at the United Nations, to further justify the war it launched against Iran two weeks ago.

At a meeting of the 15-member U.N. Security Council, which is chaired this month by the U.S., Russia and China moved unsuccessfully to block a discussion about a committee established to oversee and enforce U.N. sanctions on Iran. They were overruled 11-2 with two abstentions.

Addressing the council, U.S. envoy to the United Nations Mike Waltz accused Moscow and Beijing of seeking to protect Tehran by blocking the work of the so-called 1737 Committee.
