Iran's Revolutionary Guards on Sunday said the United States faced a choice between an "impossible" military operation or a deal with Tehran, after President Donald Trump disparaged Iran's latest peace proposal.
Negotiations between the two countries have been deadlocked since a ceasefire came into effect on April 8, with only one round of direct peace talks held so far.
Iran's foreign ministry said Tehran had submitted a 14-point plan "focused on ending the war" and that Washington had already responded to it in a message to Pakistani mediators.
