Rubio says Iran’s new supreme leader alive and 'increasingly engaging'

US Secretary of State Marco Rubio said on Tuesday that Iran's supreme leader, Mojtaba Khamenei, who was wounded in US-Israeli attacks and has not been seen in public since assuming office, is alive and increasingly active.

"I think there are indications out there that he is increasingly engaging at some level," Rubio told the Senate Foreign Relations Committee.

Mojtaba Khamenei, 56, succeeded his father Ali Khamenei, who was killed in the first wave of US-Israeli strikes that launched the war on 28 February.
