By Parisa Hafezi and Maayan Lubell DUBAI/JERUSALEM, March 9 (Reuters) - Iran on Monday named Mojtaba Khamenei to succeed his father Ali Khamenei as supreme leader, signaling that hardliners remain firmly in charge,

Son of slain Supreme Leader Ali Khamenei charged with leading Islamic Republic through biggest crisis in its history.

Iran has named Mojtaba Khamenei as Iran's new supreme leader after his father Ayatollah Ali Khamenei's was killed in U.S.-Israel airstrikes. President Donald Trump had previously said Mojtaba was an 'unacceptable' choice for the role.

U. President Donald Trump on Monday threatened to escalate the war with Iran if it blocked oil shipments from the Middle East, even as he predicted a quick end to the conflict.

Who is Ayatollah Ali Khamenei's son Mojtaba Khamenei, new supreme leader of Iran? After the reported death of Ayatollah Ali Khamenei in a US Israel attack, Irans Assembly of Experts has reportedly chosen Mojtaba Khamenei amid US Iran war tensions and political uncertainty.

Iran has elected a new leader, more than a week after Ayatollah Ali Khamenei was assassinated in an Israeli airstrike. Mojtaba Khamenei, 56, was named by a powerful council late on Sunday evening to succeed his father as supreme leader, despite US president Donald Trump’s insistence that he should have a say in the appointment.

Late last week, Iran's new supreme leader, Mojtaba Khamenei, broke his silence after days of intensifying rumours about his health and whereabouts, but it did little to put them to rest.

Mojtaba Khamenei, the son of Iran's Ayatollah Ali Khamenei, who was killed in US-Israeli strikes, has been chosen as his successor.
