Israeli forces killed a Palestinian man in fighting in the occupied West Bank, Palestinian officials said, as the death toll from clashes earlier in the city of Jenin rose to six.

The fatalities were the latest in a surge of violence that has wracked the region.

The Palestinian Health Ministry said late on Monday that 21-year-old Zakaria al-Zaoul was shot in the head in the town of Husan, west of Bethlehem.

The official Palestinian news agency Wafa reported that he was killed during clashes with the military.

The Israeli military said a suspect threw a firebomb at troops stationed along a West Bank highway near Husan. The troops responded with live fire and confirmed a hit, the army said.

Israel and the Palestinians have been gripped by months of violence, focused mainly in the West Bank, where at least 126 Palestinians have been killed this year.

Monday saw one of the fiercest days of fighting between Israeli forces and Palestinian militants near the northern West Bank city of Jenin.

The Palestinian Health Ministry said on Tuesday that 48-year-old Amjad Abu Jaas had succumbed to wounds suffered in the gun battle.

His death took to six the number of Palestinians killed in Monday’s fighting, with more than 90 others injured.

Eight Israeli soldiers were also wounded, according to the army.

The fighting saw Israel use helicopter gunships in the West Bank for the first time in several years, and Palestinian militants detonated a large roadside bomb under an Israeli armoured vehicle.

Israel has been staging near-nightly raids in the West Bank in response to a spasm of Palestinian violence early last year. Palestinian attacks against Israelis have surged during that time.

Israel says most of the Palestinian dead were militants, but stone-throwing youths protesting at the incursions and others not involved in confrontations have also been killed.

Palestinian attacks against Israelis have killed at least 20 people this year.

Israel captured the West Bank, along with east Jerusalem and the Gaza Strip, in the 1967 Middle East war. The Palestinians seek those territories for a future independent state.
