A top Israeli government minister says that following the surprising resignation of Lebanon's prime minister, Israel is planning a diplomatic offensive against Iran and its Lebanese proxy Hezbollah at the United Nations.

Intelligence Minister Yisrael Katz told The Associated Press on Thursday that he believes conditions are ripe for the world to take a stand against Iranian actions in the region.

He says Israel will work with its allies to seek better enforcement of a 2006 cease-fire agreement that called on Hezbollah to disarm and stay away from Israel's border.

Katz believes Lebanese Prime Minister Saad Hariri's resignation exposed what he called "Iran's intentions."

Hariri said last weekend that he was stepping down and accused Iran of meddling in Arab affairs.
