VIENNA-- Islamic nations at a 151-nation conference demanded Friday that Israel open its nuclear program to international purview, asserting that its undeclared atomic arms program is a threat to Mideast peace.

Unlike in recent years, however, Arab states did not push for a resolution directly targeting Israel by name after such an attempt was narrowly voted down at last year's International Atomic Energy Agency general conference.

And with few exceptions, the tone of the verbal attacks on the Jewish state appeared less confrontational. A planned IAEA meeting in November would bring Arab nations and Israel to the table to explore what can be learned from other regions that have set up zones free of weapons of mass destruction.

As in past years, the conference did pass a resolution calling on all Middle East states to adopt the Nuclear Nonproliferation Treaty in an indirect demand on Israel, the only country in the region not bound by the treaty.

But even Israel did not oppose that document, abstaining instead of voting against it after failing to have a specific paragraph that effectively singled out the Jewish state without naming it struck from the document.

In comments echoed by other Arab states before and after the vote, Syrian nuclear chief Ibrahim Othman said Israel's refusal to join the nonproliferation treaty and throw open its nuclear facilities to IAEA perusal "is a threat ... to the security and stability of the Middle Eastern states."

"The international community must bring real and genuine pressure to bear on Israel," said Othman.

Egyptian chief delegate Khaled Rahman Shamaa, speaking for developing nations -- a group traditionally supporting the Islamic bloc -- urged the meeting to address the nuclear imbalance allowing "one party to threaten its neighbors and the region."
