BBC - Iranian army chief Amir Hatami has threatened to launch a "decisive" retaliation for the killing of security chief Ali Larijani in an Israeli air strike.
"At the appropriate time and place, a decisive, deterrent, and regretful response will be given to the criminal America and the bloodthirsty Zionist regime," Hatami says in a statement.
He adds that Larijani's and the deaths of other "martyrs will be avenged".
Iran's Revolutionary Guards, which is separate from the army, says it has already launched missiles at central Israel "in revenge" for Larijani's death, AFP news agency reports.
Israel's emergency services have been responding to missiles strikes on Tel Aviv overnight.
