Iran has issued a response, through undisclosed intermediaries, to a 15-point proposal from the United States aimed at ending the conflict, according to the Tasnim news agency on Thursday. Tehran is now awaiting Washington’s reaction.

Details of the U.S. proposal remain unclear. Pakistani officials say the plan was delivered to Iran through Pakistan.

Tasnim, quoting an informed source, reports that Iran’s official reply to the proposal was sent overnight via intermediaries, and the country is now expecting a response from the U.S.
