OCCUPIED JERUSALEM, April 3 (IslamOnline & News Agencies) –Israeli occupation forces attacked a church and a mosque during incursions into the two West Bank towns of Jenin and Salfeet as Palestinians buried 15 of their dead in Ramallah’s central hospital parking lot.

Families of the dead had been unable to claim the Palestinian bodies, which were decomposing in the hospital morgue because power cuts made refrigeration impossible.

"We have found 28 bodies of people killed by Israelis so far. We are burying them in the garden because the ambulances cannot take them out," hospital administrator Mussa Abu Hmeid told Agence France-Presse (AFP).

The Palestinian Red Crescent complained of being unable to answer hundreds of calls it has received from the sick in Ramallah, while a convoy carrying its regional chief was detained and abused by the army.

"The (Israeli) behavior toward the medical teams and to the sick and injured has been appalling," Red Crescent official Husam Sharkawi told the BBC.

The Israeli incursions into Salfeet and Jenin came a day after Israel seized control of Bethlehem and another West Bank town and clashed with defenders in actions that left at least 13 Palestinians dead.

At least 30 tanks moved into Jenin from all sides. They shot heavy machine gun fire at Palestinians in the city and at the entrance of a refugee camp, witnesses said. A 27-year-old Palestinian woman was shot dead during the attack, Palestinian hospital officials said.

Tanks were taking up positions in Salfeet. More than 20 Israeli tanks moved into the town of Salfeet, located some 20 kilometers southwest of Nablus, Palestinian security sources told Agence France-Presse (AFP). The sources said Israeli occupation troops completely reoccupied the town early Wednesday.

According to the BBC’s online news service, the United Nations agency responsible for Palestinian refugees says thousands of people throughout the West Bank have been trapped with dwindling supplies of food and water.

The Israeli military operations in the West Bank began Friday. The Israeli occupation army has already reoccupied Bethlehem and Ramallah, as well as the towns of Qalqilya and Tulkarm.

Meanwhile, dozens of Palestinians were holed up inside the Church of the Nativity in Bethlehem, a monument to the birthplace of Jesus. About 20 of the Palestinians were wounded and being tended to by nuns, according to witnesses trapped in the church compound.

Bethlehem's governor and an aid worker said about 100 to 150 Palestinian men, women and children sought refuge in the church after being attacked by Israeli occupation troops firing from helicopters and from tank-mounted machine guns in the historic city.

Anton Salman -- a member of the Antonius Society, a humanitarian group in Bethlehem -- said that some of those inside were members of the Palestinian Authority security force.

At nightfall, the bodies of four Palestinians lay sprawled just off Manger Square, where the church is located.

Also in Bethlehem, an Israeli tank shell struck the main mosque of Omar Ibn Al Khattab in Bethlehem, according to witnesses.

As many as 50 Israeli troops occupied the campus of Bethlehem University, a Vatican-owned institution, said school President Vincent Malham.
