Iran`s new supreme leader has rejected de-escalation proposals conveyed to Tehran by intermediaries, demanding Israel and the United States first be "brought to their knees", a senior Iranian official said on Tuesday, writes Reuters.

Ayatollah Mojtaba Khamenei had held his first foreign policy session since being named supreme leader, and had taken a stance for revenge against the U.S. and Israel that was "very tough and serious", the official said, without clarifying whether the leader attended in person or remotely.

The senior official, who asked not to be identified, said two intermediary countries had ⁠conveyed proposals to Iran`s Foreign Ministry for "reducing tensions or ceasefire with the United States". The official did not give further details of the proposals or the intermediaries.

The supreme leader had responded that it was not "the right time for peace until the United States and Israel are brought to their knees, accept defeat, and pay compensation". The supreme leader has the final say in all matters of state in the Islamic Republic. No new images have been released of him since his selection over a week ago by a clerical assembly to replace ⁠his father, Ayatollah Ali Khamenei. Some Iranian officials have said he was lightly injured in the strikes that killed his father. U.S. officials have suggested he suffered severe injuries.
