Tel Aviv: Palestinians have appealed for an intervention by the United Nations to stop Israel's week-long campaign of arrests and air strikes following the suspected kidnapping of three Israeli teenagers in the occupied West Bank.

"The international community, including the Security Council, cannot continue to fail to act to hold Israel accountable for its flagrant breaches of the law," ambassador Riyad Mansour wrote in a letter to UN Secretary-General Ban Ki-moon.

Israeli forces continued raids in the West Bank overnight, entering 146 homes and arresting 10 members of the Hamas movement, according to an army spokesman. Troops also shut down 15 social welfare organisations that Israel says are being used as fronts for Hamas, which Prime Minister Benjamin Netanyahu has accused of kidnapping the youths.

In Gaza, militants fired a rocket into Israel early on Saturday without causing damage, the army said. Israel has been staging almost nightly air raids in the territory after repeated Palestinian rocket launchings into Israel.
