Two Palestinians have been killed in clashes with Israeli troops in the West Bank, a Palestinian health official said.
It is the latest escalation in two months of violence in which 14 Israelis have been killed, mainly in stabbings.
At least 81 Palestinians have been killed, of whom Israel says 51 were involved in assaults. The rest were killed in clashes with security forces.
On Saturday Israel arrested a Palestinian suspect in the killing of two Israelis in a drive-by shooting in the West Bank on Friday.
The Shin Bet internal security service said forces also seized a weapon and vehicle used in the shooting.
It said the suspect admitted to involvement in the attack, which killed a rabbi and his son who were driving with family south of the city of Hebron.
