The latest deaths take the number of Palestinians killed by Israeli forces in the occupied West Bank in January to 17.

Jawad Fareed Bawaqneh, a 57-year-old father of six and teacher at a local school, was killed on Thursday morning in the Jenin refugee camp, local journalists told Al Jazeera, as well as Adham Jabareen, a 28-year-old fighter with the Jenin Brigades armed resistance group.

The Palestinian Ministry of Health confirmed the names and ages of the deceased men at 7am (04:00 GMT).

At least four other Palestinians were injured by live ammunition.

Local journalist and resident Mujahed al-Saadi, who spoke to witnesses, told Al Jazeera that Bawaqneh, the teacher, was killed on the street in front of his home as he was attempting to help Jabareen after the latter had been shot.

“The teacher was killed when the resistance fighter was injured under his house – Bawaqneh went to bring Adham into his house to give him treatment, when the sniper shot him directly in the chest,” al-Saadi said.

Bawaqneh was a teacher at a boys’ high school in Jenin city, the Palestinian Ministry of Education said in a statement mourning him.

The Israeli army launched a large-scale raid with more than 70 armed vehicles into the Jenin refugee camp located inside the city at 2:30am (23:00 GMT on Wednesday) and withdrew three and a half hours later.

Special forces descended into the camp on foot, snipers positioned themselves on rooftops and roadblocks were set up in and around Jenin and the camp. Fighting with Palestinian fighters broke out soon after the raid began.

Al-Saadi said Israeli forces “raided the camp from all sides” and arrested at least six men.

During the raid, the army reportedly attempted to arrest Khaled Abu Zaineh – a leader in the Gaza-based Palestinian Islamic Jihad (PIJ) armed group.

“They raided and searched a number of homes belonging to the family, and they arrested two of his sons,” al-Saadi said. Local media reported that Abu Zaineh appeared in Jenin shortly after and confirmed that two of his sons had been arrested.

Israeli media said one soldier was lightly injured from a homemade explosive device detonated by Palestinian fighters.

The killing of the two men brings the number of Palestinians killed by the Israeli army in the West Bank in the 19 days since 2023 began to 17, including four children. Nine of them were from Jenin.

The killings come as a result of intensified near-daily Israeli army raids that have persisted for close to a year under the banner of crushing limited Palestinian armed resistance in the northern West Bank.

Israeli forces have killed civilians confronting them during raids, uninvolved bystanders, as well as Palestinian fighters in targeted assassinations and armed clashes.

The United Nations said 2022 was the deadliest year for Palestinians in the West Bank since 2006. More than 30 children were among the 171 Palestinians killed in the West Bank last year, and at least 9,000 other Palestinians were injured.

Separately, 53 other Palestinians, including 17 children, were killed during a three-day assault on the besieged Gaza Strip in August, bringing the total number of Palestinian deaths last year to 224.
