Israeli Prime Minister Benjamin Netanyahu warned Washington on Monday that an emerging nuclear deal with Iran could threaten his country's very survival, but insisted Israel-U.S. relations remain solid.

"You are here to tell the world that reports of the demise of the U.S. relationship is not only premature, but it is wrong," the Israeli leader told delegates to a packed pro-Israel conference in Washington.

The Palestinians are to lodge their first complaint against Israel for alleged war crimes at the International Criminal Court on April 1, a senior official told Agence France-Presse on Monday.

"One of the first important steps will be filing a complaint against Israel at the ICC on April 1 over the (2014) Gaza war and settlement activity," said Mohammed Shtayyeh, a member of the executive committee of the Palestine Liberation Organization (PLO).

An Israeli military vessel violated Lebanon's territorial waters at dawn Monday and threatened a Lebanese fishing boat.

“In a new violation of Lebanese sovereignty and (U.N. Security Council) Resolution 1701, a gunboat belonging to the Israeli enemy violated the Lebanese territorial waters off Ras al-Naqoura at 3:40 am,” the Lebanese army said in a statement.

U.S. Secretary of State John Kerry on Monday warned Israel's prime minister against revealing details at his upcoming speech to U.S. Congress of an Iran nuclear deal that world powers are in the process of negotiating.

While he did not mention Benjamin Netanyahu by name, Kerry told reporters in Geneva he was "concerned by reports" that "selective details" of the deal aimed at curbing Tehran's nuclear program would be revealed in the coming days.

U.S. Secretary of State John Kerry on Monday launched a staunch defense of Israel at the U.N. rights body, despite strained ties with the Jewish state over nuclear negotiations with Iran.

The Human Rights Council (HRC) has long been accused of bias towards Israel, which is the only country to have a specific agenda item obliging participants to discuss the Jewish state's rights record at every session held.

Three Israelis were on Monday charged with smuggling goods into the Gaza Strip knowing they would be used by Hamas to bolster its military infrastructure, officials said.

Micha Peretz, Yehoram Alon and another man whose name has not been released were indicted at Beersheba District Court for trade worth millions of dollars with a Palestinian merchant in Gaza, while fully aware he was transferring the materials to Hamas.

After years of strained relations over the Syrian conflict, Palestinian Islamist group Hamas is looking to mend ties with its traditional backer Iran. But reconciliation is proving far from simple.

The outbreak of Syria's civil war nearly four years ago provoked a rupture between Hamas and Iran, after the movement threw its support behind rebels fighting President Bashar Assad, a close ally of Tehran.

Israel's army said it launched a "surprise exercise" Sunday calling up thousands of reservists for its central region of operations that includes the West Bank.

The military said in a statement that it was mobilizing "forces including some 13,000 reserves, 3,000 of whom will physically report for active duty."

Israeli Prime Minister Benjamin Netanyahu is "welcome" to deliver his US speech, Secretary of State John Kerry said Sunday, insisting that Washington is eager to avoid a "political football" over the controversial visit.

"The Prime Minister of Israel is welcome to speak in the United States obviously and we have a closer relationship with Israel right now in terms of security than in any time in history," Kerry told ABC television's "This Week" program.

Israeli Prime Minister Benjamin Netanyahu was due in Washington Sunday on what he has called a "historic" quest to stop an international nuclear deal with Iran that the United States is determined to pursue.

Netanyahu's controversial 48-hour visit has stoked discord with U.S. President Barack Obama and brought bilateral relations to their lowest point in years.
