JERUSALEM – Israel's prime minister on Sunday urged the international community to get tougher against Iran, saying that without a "clear red line," Tehran will not halt its nuclear program.

The tough language from Prime Minister Benjamin Netanyahu reflected differences that have emerged between Israel and its allies, particularly the U.S., over how to deal with Iran.

Israel has warned that the Iranians are quickly approaching weapons capability and that the threat of force must be seriously considered. The U.S. says sanctions and international diplomacy must be given more time to work.
