Israeli forces traded gunfire with Palestinians on Thursday, the military said, in the fiercest street battles in the occupied West Bank since the search began for three Israeli teenagers missing for a week.

Hospital officials said three Palestinians suffered bullet wounds in the overnight clashes in Jenin, a militant stronghold and the scene of deadly fighting during a Palestinian uprising a decade ago. There were no reported Israeli casualties.

A military statement said about 300 Palestinians, including some who "hurled explosives and opened fire," confronted soldiers who entered Jenin looking for the three seminary students.
