A volley of shots was fired at a border police checkpoint north of Jerusalem Thursday morning.

There were no injuries reported in the shooting, although several rounds hit the manned position.

Soldiers who searched the area around the post at the entrance to the Qalandiya refugee camp found 29 bullet casings at the source of the gunfire, an IDF spokesman said.

The Qalandiya checkpoint is a frequent flashpoint for clashes between IDF forces and Palestinian protesters.

In the north Jerusalem neighborhood of Pisgat Ze’ev, a soldier claimed Thursday morning that he was stabbed by a group of Arabs.

The soldier was lightly injured in his leg and taken for treatment.

He later retracted his story and said the wound was from a fall.

Over the weekend three Palestinian extremist groups threatened to avenge attacks after three Palestinians killed were by Israeli forces on Saturday in the Jenin refugee camp during an operation to capture a wanted Hamas terrorist.

In a rare joint statement, the three groups — Hamas, Islamic Jihad and Fatah’s military wing, the Al-Aqsa Martyrs’ Brigades – warned of retribution against Israel and against the Palestinian Authority leadership for allegedly cooperating with Israel.

Saturday’s incident started with an Israeli raid, which the military said aimed to arrest Hamza Abu al-Hija, a 22-year-old Hamas operative wanted for involvement in shooting and bombing attacks against Israelis.

Within minutes, hundreds of angry residents and gunmen gathered and attacked the soldiers. The troops opened fire in self-defense, killing two Palestinians and wounding several more.
