Four Palestinians died on Friday afternoon after being shot in clashes with Israeli security forces during protests in the West Bank and Gaza Strip, Palestinian officials said, as thousands of Palestinians demonstrated for a second week against Washington’s recognition of Jerusalem as Israel’s capital.

A Palestinian who stabbed an Israeli Border Police officer in the upper torso before being shot, died on Friday evening, the Palestinian Authority health ministry said, naming him as Mohammed Aqal, 29.

Aqal stabbed and moderately wounded the Israeli officer, who was later reported to be in stable condition in the hospital. When officers noticed he was wearing what appeared to be a suicide bomb belt, they shot him again, fearing he would detonate it, police said. He was taken away by Palestinian medics and later died of his wounds, the health ministry said, as reported by The Times of Israel. Hadashot news said the suicide belt was a model that did not contain actual explosives.

The Israel Defense Forces did not immediately comment. Earlier, the army said it opened fire on the “main instigators” of violent protests at the Gaza border after they failed to heed repeated calls to stop approaching the fence. Israel’s Army Radio reported 3,500 Gazans demonstrated at nine locations along the fence around the Hamas-run enclave, lighting fires and throwing rocks.
