Five Palestinians including two senior leaders of a Palestinian resistance group were killed in Gaza City, on Thursday, while four Israelis died in an explosion at a bus stop outside Tel Aviv. Leader of the Palestinian Islamic Jihad resistance group Moqled Hamid, an associate and at least three other Palestinians were killed and seven people wounded, in a missile attack by Israeli helicopter gunships on a car in Gaza city. Moqled was the commander of Islamic Jihad's armed wing. The associate was a top deputy in Jihad's Jerusalem Brigades. Palestinian medical sources and witnesses said the gunships fired two missiles at a car on al-Jalah Street, in a northern district of the city. The air strike was followed 40 minutes later by a bomb detonated by a Palestinian resistance fighter on a bus stop outside Israel's main metropolis Tel Aviv. Israeli police said the bomber killed three women and one man at a bus stop on the highway out of the coastal metropolis of Tel Aviv. The Popular Front for the Liberation of Palestine claimed responsibility for the bombing, calling it revenge for Israeli raids last week on the West Bank city of Nablus. The Israeli government said Thursday's attack outside Tel Aviv, the first big bombing in almost three months, showed Palestinians were ever ready to strike in the heart of the Jewish state. Palestinian Prime Minister Ahmed Qurie called for total calm to help a beleaguered US-led "road map" for peace, but Palestinian fighters vowed bloody revenge for the helicopter strike that killed the commander of Islamic Jihad's military wing. "The assassination of the chief leader of the Jerusalem Brigades will not pass without a deterrent, a strong and an earthquake-like response," an Islamic Jihad statement said. Contacts have been building to arrange a summit between Qurie and Sharon, but the Palestinians shelved the last meeting to discuss preparations after an Israeli raid in the Gaza Strip left nine dead on Tuesday. Israel slapped a blockade on the occupied West Bank and Gaza Strip. A military spokesperson said they would decide on Friday how to allow out hundreds of pilgrims who flocked to the West Bank city of Bethlehem for Christmas. **PHOTO*** Tel Aviv blast responsibility claimed by PFLP (The Popular Front for the Liberation of Palestine)
