Some intelligence reports say that Hizballah leader Hassan Nasrallah may be hiding in the Iranian Embassy.

Intelligence reports indicate the leader of Hezbollah is hiding in a foreign mission in Beirut, possibly the Iranian Embassy, according to U.S. and Israeli officials.

Israeli military and intelligence forces are continuing to hunt for Sheik Hassan Nasrallah, Hezbollah’s secretary-general, who fled his headquarters in Beirut shortly before Israeli jets bombed the building last week.

“We think he is in an embassy,” said one U.S. official with access to the intelligence reports, while Israeli intelligence speculates Sheik Nasrallah is hiding in the Iranian Embassy.

If confirmed, the reports could lead to an Israeli air strike on the embassy, possibly leading to a widening of the conflict, said officials who spoke on the condition of anonymity. Foreign embassies are sovereign territory and an attack on an embassy could be considered an act of war.
