'More confrontational': Iran's new hardline security leadership

Earlier this month Iranian supreme leader Mojtaba Khamenei reshuffled Tehran's top security team, putting his own personal stamp on the appointments and readying the Islamic republic for a long-term confrontation with the United States.

Khamenei, in power since his father Ali Khamenei was killed at the start of the US-Israeli war against Iran in February, has yet to be seen in public since taking on the top job and his health and influence remain uncertain.
