A Palestinian terrorist was shot dead on Wednesday after stabbing a security guard at the entrance to a settlement in the West Bank, the Israeli military said.

The civilian guard, stationed at the Karmei Tzur settlement north of the city of Hebron, was slightly wounded. Another security guard shot and killed the attacker, the military said in a statement.

Late on Tuesday, Israeli forces shot dead at least one Palestinian during a raid in the West Bank city of Nablus that led to confrontations with residents, Palestinian health officials said.

In a statement, the military said its troops had been searching for a terrorist who fatally stabbed an Israeli man at the entrance to the city of Ariel in the West Bank on Monday.

“During the activity, a violent riot was instigated as approximately 500 Palestinians hurled rocks, fire bombs and explosive devices and fired live rounds at IDF (Israel Defence Forces) soldiers, and in addition the rioters built rock barriers,” a military statement said.

The troops “responded with riot dispersal means and fired warning shots in the air”, it said. “A report regarding a Palestinian being killed and several injured… is being reviewed.”

The Palestinian Health Ministry put the number of Palestinians wounded at 29. The Palestinian Red Crescent ambulance service said stone-throwers had clashed with the soldiers.

The attacker in the Ariel incident was an Arab citizen of Israel and Israeli media reports said his father is a Nablus resident. The military said the suspect was not apprehended in the operation and seven people were detained for questioning.

Earlier on Tuesday, Israeli forces killed a terrorist in the West Bank village of Yamoun and said he was the head of a cell responsible for an ambush in which an Israeli man was shot dead on Jan. 9.

Israel had been looking for the final member of the cell which it said killed Rabbi Raziel Shevach in a drive-by shooting. Commandos had already killed one of the terrorists involved and captured another.
