Israeli forces have killed at least nine Palestinians and injured dozens more in overnight raids in the occupied West Bank. At least five were killed in Jenin where the Israeli military blew up the homes of two wanted Palestinians and destroyed at least three monuments in and near the Jenin refugee camp, local sources told Al Jazeera on Friday. The raid, which is the sixth in the past two weeks on Jenin, started at about 22:00 GMT and lasted about nine hours, the sources said. The Jenin refugee camp has long been viewed as a bastion of Palestinian resistance, more so in the past two years when fighters started working in tandem to confront the Israeli occupation forces. In al-Fawwar refugee camp south of Hebron, Israeli forces confronted Palestinians for nearly three hours, killing two people and injuring at least five others, medical sources told Al Jazeera. Israeli forces detained at least three Palestinians, including the parents of a wanted Palestinian – a tactic they have been using for years, to pressure Palestinians to hand themselves in – according to local sources. In the Qalandiya refugee camp north of occupied East Jerusalem, one Palestinian was killed and several others were injured in an early morning raid. Another Palestinian died of wounds he sustained on Wednesday during an Israeli raid on Nablus. Israeli forces are now raiding Tulkarm and the confrontations are continuing.
