Iranian Supreme Leader Ayatollah Ali Khamenei issued an order to strike Israel directly in retaliation for the assassination of Hamas chief Ismail Haniyeh, according to a report.

Three Iranian officials, including two members of the Islamic Revolutionary Guards Corps, told the New York Times the order was issued after an emergency meeting of Iran’s Supreme National Security Council on Wednesday. The reported order comes as the Iranian government publicly vowed retaliation after the head of one of its allies was killed in the heart of its capital.
