Israel has arrested a Palestinian suspect in the killing of two Israelis in a drive-by shooting in the West Bank.

The Shin Bet internal security service said Sunday that forces also seized a weapon and vehicle used in the shooting. It says the suspect admitted to involvement in Friday's attack, which killed a rabbi and his son, who were driving with family south of the city of Hebron.

Israeli media say more than a dozen Palestinians were arrested in connection with the attack over the weekend.

The shooting was the latest escalation in two months of Palestinian attacks, mainly stabbings, which have killed 14 Israelis. 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.
