Gaza: Islamic Jihad fired rockets into Israel on Thursday, ending a week-long Egyptian-brokered moratorium in what it called an "initial" response to deadly Israeli raids in the West Bank.

No one was hurt by the salvo just after midnight against the border town of Sderot.

Islamic Jihad had vowed revenge after Israeli troops killed four of its members two West Bank towns on Wednesday.

At least four rockets hit Sderot on Thursday. A house was damaged but no casualties caused, the Israeli military said.

As part of any truce, Hamas is demanding a say in the future functioning of the coastal territory's border crossings, a condition rejected by Israel.

"There must be a commitment by Israel to end all acts of aggression against our people, assassinations, killings and raids, and lift the (Gaza) siege and reopen the crossings," Ismail Haniyeh, leader of Hamas's administration in Gaza, said in a speech.

A truce, he said, should be "reciprocal, comprehensive and simultaneous", approved by other factions, and apply to Gaza and the West Bank -- territories where Palestinians seek statehood.
