Israel's center-right government will support U.S. efforts to revive peace talks with the Palestinians, despite hardline positions held by ministers and coalition parties, a prominent MP said on Monday.

"If (Prime Minister Benjamin) Netanyahu goes on the path that U.S. Secretary of State Kerry is encouraging... he will have the full support of... the majority of the parliament," Ofer Shelah, a member of the powerful Yesh Atid party told army radio.

Israel announced on Monday it was calling off a United Nations investigative mission to the Old City in annexed east Jerusalem because of Palestinian efforts to politicize the visit.

"Israel has canceled the delegation," which was due to have arrived the same day, a foreign ministry official told Agence France Presse

President Michel Suleiman denied on Monday receiving a warning from Israel that it would destroy Lebanon in case of a Hizbullah attack on the Jewish state.

Suleiman's press office said that the president hasn't received such a warning “although Israeli threats and violations of Lebanese airspace never stop.”

An Egyptian police camp came under fire with heavy weapons on Monday in the Sinai, where tensions have been running high since last week's kidnapping of security personnel, a security official said.

The official, quoted by state news agency MENA, said assailants opened fire "for 25 minutes using heavy weapons" against El-Ahrash camp in the north of the Sinai Peninsula, without reporting casualties.

Shots fired from Syria hit the central Israeli-occupied Golan Heights overnight, a military spokeswoman said Monday morning, causing no harm or damage.

According to the spokeswoman, the shots were from small arms, and "most likely were stray bullets, we don't know if it was intentional."

President Michel Suleiman on Sunday condemned the rocket attack from Syrian territory on the Bekaa area of Hermel and denounced the Israeli mock raids over southern Lebanon.

In a press release, Suleiman stressed the need for “all warring parties in Syria to respect Lebanon's sovereignty and avoid military acts against Lebanese border areas that are targeting peaceful citizens.”

Israel is "acting" to prevent Syrian weapons reaching Hizbullah and will continue to do so, Prime Minister Benjamin Netanyahu said on Sunday.

His remarks came two weeks after Israel carried out air strikes near Damascus, which a senior Israeli source said were aimed at preventing the transfer of sophisticated Iranian arms to Hizbullah.

Advanced S-300 Russian air defense weapons, which Moscow has pledged to deliver to Syria, could reach Hizbullah and beyond, a senior Israeli defense official has warned.

Amos Gilad, head of the diplomatic-security branch of Israel's defense ministry, told Channel 2 that such a transfer is a threat to the Jewish state, to the U.S. and to the Persian Gulf.

Iran hanged two convicted spies on Sunday, one found guilty of working for Israel, the other for the United States, the Tehran prosecutor's office announced.

Mohammad Heydari was convicted of "receiving payment to provide intelligence on various security issues and national secrets in repeated meetings with the Mossad," Israel's intelligence agency, a statement said.

Germany's foreign minister said on Saturday his country was prepared to help create conditions for a resumption of peace talks between Israel and the Palestinians.

Guido Westerwelle, on a two-day visit to Israel and the Palestinian territories, was quoted by a foreign ministry statement as saying "Germany is ready to help create a climate of confidence" that would permit talks to resume.
