No militant group has claimed responsibility yet for the shooting and police were still searching for the gunmen's car. The attack occurred just hours before Israel's temporary construction freeze in West Bank settlements was set to expire.

Later Sunday evening, an Israeli police officer was lightly wounded when he was hit in the head by a rock thrown by Palestinian demonstrators in East Jerusalem. The officers were in the area breaking up a fight between local residents.

Also on Sunday, Palestinians hurled firebombs at Border Police officers patrolling in an East Jerusalem parking lot.

None of the officers was wounded in the incident, but three Palestinians were detained for questioning. Three others firebombs were found in the immediate vicinity.

On August 31, four Israelis were killed after Hamas terrorists opened fire on their cars on Route 60 in the West Bank. The four victims were residents of the Beit Hagai settlement.

In a separate attack a day leader, two Israelis were wounded - one of them seriously - when Palestinian gunman ambushed their car near the settlement of Kochav Hashachar, east of the West Bank city of Ramallah.

That spate of shootings coincided with the launch of U.S.-backed direct peace talks between Israel and the Palestinians in Washington. The Islamist Palestinian faction Hamas have come out vocally against the talks, claiming responsibility for the shooting attacks and warning of further attacks.
