RAMALLAH, West Bank — Three Palestinians were killed during a firefight with Israeli security forces who had entered a flash point city in the occupied West Bank, Palestinian officials said.
One of the men who died was unarmed, according to Palestinian health and security officials, who said several Palestinian gunmen were also wounded.
The violence erupted when Israeli security officers who had entered the town of Nablus were spotted by Palestinian security officers and militants, according to a spokesman for the Palestinian Fatah movement.
The Israeli military said that its forces were operating in Nablus but gave no further details.
Nablus has been a flash point for violence since Israel began a crackdown in the West Bank in March in response to a series of attacks by Palestinians in Israel.
Nabil Abu Rudeineh, the spokesman for President Mahmoud Abbas of the Palestinian Authority, said that Mr. Abbas’s office had reached out to the United States to ask for its help in ending the Israeli campaign.
“All of this will have dangerous and destructive consequences,” Abu Rudeineh said on Palestine TV.
