Reports from the West Bank City of Jenin say an Israeli aircraft fired a missile at a car killing at least three Palestinian militants.
Palestinian witnesses and medics said four men were in the car when it was attacked in the centre of the city.
Palestinians identified the men as members of al-Aqsa Martyrs Brigades, an armed wing of Palestinian President Yasser Arafat's Fatah faction.
There was no immediate report on the status of the fourth man. The Israeli army has declined to comment.
