By ILAN BEN ZION and MAJDI MOHAMMED (Associated Press) JENIN REFUGEE CAMP, West Bank (AP) — The Israeli military raided the West Bank city of Jenin on Monday, striking the refugee camp with helicopter gunships. This has triggered the most ferocious fighting in the occupied territory in years, killing five Palestinians, including a 15-year-old boy, and wounding over 91 others, health officials said, including 12 in critical condition. Seven Israeli soldiers were also wounded, the army said. During nearly 10 hours of fighting, Israeli security forces faced off against Palestinian militants with gunfire, armored bulldozers and missile fire from at least one Apache helicopter. The Israeli military said that helicopters fired at Palestinian gunmen as security forces tried to extract damaged vehicles from the camp. Israeli security forces rarely deploy airpower to strike Palestinian militant targets in the West Bank. It was the first such use of a helicopter gunship in the occupied West Bank since the second Palestinian uprising some two decades ago, Israeli media reported.
