Palestinian Prime Minister Rami Hamdallah was not injured on Saturday when the lead security vehicle in his motorcade collided head on with a car driven by Israeli settlers on a West Bank road east of Bethlehem, witnesses and Palestinian medics said.

An Israeli car carrying three people ran into Hamdallah's motorcade while he was returning from a visit to Hebron, witnesses said.

Medics from the Palestinian Red Cross and the Israeli ambulance service said the three Israelis and three Palestinian security officials were lightly to moderately injured.

The collision was described as an accident; an attempt on Hamdallah's life was ruled out. The injured were sent to Palestinian and Israeli hospitals.

Ehab Bseiso, the prime minister's spokesman, said Hamdallah surveyed the injured at the scene and inspected the damaged cars before proceeding to Ramallah.
