Israeli forces swept into the Palestinians' administrative capital of Ramallah in the occupied West Bank overnight, killing a 16-year-old in a refugee camp during their biggest raid into the city in years, Palestinian sources have said.

Witnesses in Ramallah said on Monday Israeli forces had driven dozens of military vehicles into the city, the headquarters of the Palestinian Authority (PA) led by President Mahmoud Abbas which exercises limited self-rule over parts of the West Bank.

The Palestinian Health Ministry said Israeli forces shot and killed 16-year-old Mustafa Abu Shalbak while raiding Am'ari refugee camp. Reuters television footage showed military vehicles leaving the camp as troops with rifles stood nearby.

The Palestinian news agency WAFA said confrontations broke out as Israeli forces stormed the camp, "during which live bullets were fired at Palestinian youths", wounding Abu Shalbak in the neck and chest.

The Israeli military did not immediately respond to a request for comment.

The Palestinian Foreign Ministry said Israeli occupation authorities were making the lives of Palestinians in the occupied West Bank "an unbearable hell" with actions including raids, detentions, and movement restrictions, warning of "serious risks" of plunging the West Bank into "violence and anarchy".

Surging violence

Violence has surged across the occupied West Bank in parallel to the Gaza war, with at least 400 Palestinians killed in clashes with Israeli soldiers and settlers.

Israeli forces also tore up a main road by the Nur Shams refugee camp in the Tulkarm area, witnesses said.

"Every time they enter the camp they destroy more than the previous time," said Ibrahim Hamarsheh, a resident of the camp who heads the Tulkarm branch of the Palestinian Prisoners' Club, which advocates for Palestinians in Israeli jails.

He said Israeli forces had also bulldozed roads in the camp.

WAFA also reported that Israeli forces had stormed the West Bank city of Nablus, and blew up the home of a man previously accused by Israel of carrying out an attack in which a British-Israeli mother and her two daughters were killed in April in the West Bank.

The man, Moaz Al Masri, was killed by Israeli forces in Nablus last May.

Israeli forces detained at least 55 Palestinians in raids across the West Bank overnight, according to The Palestinian Prisoners Club.
