Palestinian authorities say Israeli troops killed two Palestinian militants Sunday in the West Bank city of Nablus.
Officials said the two were members of the Al Aqsa Martyrs Brigades, a violent offshoot of President Mahmoud Abbas' Fatah movement.
Troops surrounded the house they were hiding in and killed them during a heavy exchange of fire.
On Saturday, Israeli forces killed six Palestinians during raids in the West Bank and an air strike in the Gaza Strip.
The Israeli military says its aircraft fired on a car carrying Palestinian militants who had been firing rockets from Gaza into southern Israel. One member of Islamic Jihad was killed, and another was wounded.
One of the militants' rockets hit a house in the Israeli border town of Sderot. An ambulance service said two Israelis were slightly hurt.
In the West Bank city of Jenin, officials said Israeli troops killed three Palestinian militants traveling in a car.
Palestinian officials say Israeli troops also shot and killed a Palestinian policeman and a 17-year-old girl. Officials say the girl was shot as she stood at the window of her house. Israeli officials said they were investigating the incident.
Saturday's fighting was among the worst since Israel and the Palestinians agreed to a ceasefire in November.
