Raiding Israeli forces killed six Palestinian militants and four civilians today, the highest single-day Palestinian death toll in the West Bank for more than two years, witnesses and medics said.
Israeli Prime Minister Ariel Sharon added to pessimism about peace prospects, declaring that Israel was not following the US-backed "road map" plan and could stay in the occupied West Bank for a long time after a planned pullout from Gaza in 2005.
Mr Sharon spelled out what various Israeli officials have been suggesting for months.
The "road map" was derailed some time ago amid persistent violence and recrimination on both sides.
Israeli forces, sustaining pressure on Palestinian militants in advance of "disengagement" from Gaza and a small wedge of the West Bank next year, killed five militants and an 11-year-old girl bystander during a raid into the West Bank city of Nablus.
Four of the slain gunmen were from the al-Aqsa Martyrs Brigades, part of Palestinian President Yasser Arafat's Fatah faction, and the other from the Democratic Front for the Liberation of Palestine, witnesses said.
Israeli military sources said five "senior terrorists" had been targeted in the pre-dawn operation.
Hours later, Israeli special forces backed up by helicopter gunships killed four Palestinians, a militant, a policeman and two civilians, at a car repair shop in the northern city of Jenin, according to local witnesses and medics.
They had earlier said all four dead were militants.
An army spokeswoman said all the Palestinians were armed and they were shot inside a cafe. Two others were arrested.
The two raids killed the most Palestinians in one day since April 2002, at the height of a massive Israeli offensive against militants waging a now four-year-old revolt.
"This is a big crime that cannot be forgiven and is part of Israeli determination to escalate aggression," Mr Arafat said at his Ramallah headquarters where Israeli forces confine him.
Israel has cranked up efforts to eliminate militants to prevent them proclaiming victory once Sharon carries out his plan to "disengage" from conflict by evacuating more than 8,000 settlers from Gaza and the northern West Bank in 2005.
