DUBAI/JERUSALEM/WASHINGTON, March 1 - Israel said it had launched another wave of strikes on Iran on Sunday, as Iranians faced uncertainty after the killing of their supreme leader in U.S. and Israeli attacks that threatened to destabilize the wider Middle East.

Hours after the United States and Israel said that an air strike killed Ayatollah Ali Khamenei as part of the most ambitious series of attacks on Iran in decades, Iranian state media confirmed the 86-year-old leader's death on Saturday.
