An opinion poll suggests widespread Israeli skepticism over the international community's recent nuclear deal with Iran.

A poll by the Israel Democracy Institute think tank and Tel Aviv University found 77 percent of Israelis don't believe the deal will prevent Iran from developing a nuclear weapon.

Iran agreed to freeze parts of its nuclear program in return for relief from Western sanctions while the sides try to negotiate a final settlement in the next six months. Prime Minister Benjamin Netanyahu has sharply criticized the deal as not tough enough on Iran.

U.S. Secretary of State John Kerry arrives in the region Wednesday to discuss the Iran deal with Netanyahu and to advance Israeli-Palestinian peace talks.

Monday's poll surveyed 601 Israelis and had a margin of error of 4.5 percentage points.
