Reuters - Iran�s ambassador to the United Nations dismissed as �unbelievable� what he said was President Donald Trump�s call for cooperation given Washington was imposing sanctions on Tehran, Iran�s state news agency IRNA reported on Thursday.

Majid Takht Ravanchi, in what appeared to be Iran�s first official reaction to Trump�s address after an Iranian missile attack on Iraqi bases housing U.S. troops, was quoted as saying Washington had �initiated a new series of escalation and animosity with Iran� by killing an Iranian general on Jan. 3.
