A senior Palestinian official on Thursday rejected US moves to extend an April deadline for nine months of hard-won talks with Israel to culminate in a framework peace deal.

"There is no meaning to prolonging the negotiation, even for one more additional hour, if Israel, represented by its current government, continues to disregard international law," Palestinian chief negotiator Saeb Erakat told Agence France Presse.

The Mustaqbal parliamentary bloc hoped on Thursday that government's policy statement would focus on national principles that enjoyed consensus among the rival political powers.

It said after its weekly meeting: “The ministerial statement should adhere to the Baabda Declaration and Bkirki charter and commit to the policy of disassociation from regional crises.”

German Chancellor Angela Merkel began a visit to Britain Thursday, where she will make a historic speech to parliament, hold talks on the EU and Ukraine with Prime Minister David Cameron and take tea with the queen.

The eyes of Europe will be on how the continent's most powerful politician deals with Cameron's efforts to win her support for his bid to reform the bloc ahead of a referendum on Britain's membership.

Israel has killed dozens of Palestinian civilians in the West Bank over the past three years showing a "callous disregard for human life," a report by Amnesty International said Thursday.

Israel responded by saying the London-based rights group did not take into account the increasing number of attacks on its forces in the past year or seek comment until the eve of publication.

Israeli troops along the border with Lebanon were on high alert Wednesday night after Hizbullah threatened action over what it said was an Israeli air raid, Israel's army radio said.

"The military ordered farmers to stay away from the border... and there was movement of military vehicles around border communities," the radio said.

Israel has successfully completed tests of a new missile defense system for commercial aircraft and plans to start fitting it to its passenger fleet, the defense ministry said on Wednesday.

It said the automatic laser-based "SkyShield" system detects shoulder-fired anti-aircraft missiles and also scrambles their guidance systems, rendering them harmless.

The 57-member Organization of Islamic Cooperation on Wednesday condemned as a "dangerous escalation" a debate by Israel's parliament on allowing Jewish prayer at Jerusalem's sensitive Al-Aqsa mosque compound.

OIC Secretary General Iyad Madani described the move as "a dangerous and unprecedented step that comes as part of Israel's racist policy ... aiming to Judaise Jerusalem."

Jordan warned Wednesday that it might review a 1994 peace treaty with Israel after Israeli MPs began a debate on allowing Jewish prayers at Jerusalem's sensitive Al-Aqsa mosque compound.

"If Israel wants to violate the peace treaty in this issue, the entire treaty, its articles, details and wording will be put on the table," Prime Minister Abdullah Nsur told Qatar's Al-Watan newspaper in an interview.

United Nations Special Coordinator for Lebanon Derek Plumbly urged on Wednesday Lebanon and Israel to exercise restraint after an Israeli air raid two days earlier on one Hizbullah positions in Lebanon.

“I don't have any direct information about the matter,” Plumbly told reporters after talks with Foreign Minister Jebran Bassil at the Bustros Palace.

President Michel Suleiman has ordered that the necessary measures be taken in order to file a complaint to the United Nations Security Council over Israel's strike against a Hizbullah position on Monday.

He tasked Foreign Minister Jebran Bassil to gather all available information on the strike ahead of filing the complaint.
