Rubio says Mojtaba Khamenei alive and 'increasingly engaging'

US Secretary of State Marco Rubio confirms Iran's supreme leader Mojtaba Khamenei is alive and active. Talks to end a three-month war have stalled. Rubio hopes for a deal if Iran limits its nuclear program and reopens the Strait of Hormuz. Sanctions relief depends on Iran abandoning enrichment activities. The prospect for a deal is imminent.
