Israeli forces have killed 14 Palestinians during a raid in the occupied West Bank, while an ambulance driver was killed as he went to pick up wounded from a separate attack by violent Jewish settlers, Reuters reports citing Palestinian authorities.

Israeli forces began an extended raid in the early hours of Friday in the Nur Shams area, near the flashpoint Palestinian city of Tulkarm and were still exchanging fire with armed fighters well into Saturday.

Israeli military vehicles massed and bursts of gunfire were heard, while at least three drones were seen hovering above Nur Shams, an area housing refugees and their descendants from the 1948 war that accompanied the creation of the state of Israel.

The Tulkarm Brigades, which groups forces from numerous Palestinian factions, said its fighters exchanged fire with Israeli forces on Saturday.

Palestinian health authorities said at least 14 Palestinians, two of whom were identified by Palestinian sources and officials as a gunman and a 16-year-old boy, were killed during the raid, one of the heaviest casualty totals in the West Bank in months. Another man was killed on Friday.

In a separate incident, the Palestinian health ministry said a 50-year-old ambulance driver was killed by Israeli gunfire near the village of Al-Sawiya, south of the city of Nablus, as he was making his way to transport people injured during the attack on the village.
