TEHRAN, March 2 (Reuters) - Iran's supreme leader on Sunday called on Muslims to rise up and their leaders to hit Israel "in the face with their nations' anger" over the Jewish state's offensive in Gaza that has killed more than 100 Palestinians.

Supreme Leader Ayatollah Ali Khamenei also blamed Iran's other arch foe, the United States, for the violence in Gaza.

"It is with the support of that (the U.S.) oppressive government that the Zionists (Israel) are committing these unforgivable sins with impudence," a statement read out on state television quoted him as saying.

"The Islamic (people) must rise and the Islamic leaders must hit the occupying regime in the face with their nations' anger," Khamenei's statement said. (Editing by Caroline Drees)
