Israeli forces have arrested a number of Palestinians after raiding Jenin Camp in the occupied West Bank, Al Jazeera's correspondent reports.
Armed clashes erupted on Thursday in the camp between activists of al-Aqsa Martyrs Brigade and Israeli forces, Ali al-Sumodi said in his report from Jenin.
Israeli forces backed by more than 20 military vehicles stormed Jenin Camp at dawn, carrying out raid and search operations, he said.
The forces surrounded houses in the camp including those of activists of al-Aqsa Martyrs Brigade, al-Quds Brigade and Hamas, residents said.
The operation finished on Thursday morning after Israeli forces arrested a number of Palestinians, including two Hamas activists.
Witness said Israeli forces threatened repeated raids if they continued to harbour and support what they claimed were "wanted Palestinians".
Targetted killing
The raid comes a day after Israeli special forces ambushed and killed an Islamic Jihad commander in the city of Jenin on Wednesday.
25 year old Mahmoud Abu Obeid was shot dead by Israeli special forces disguised as Palestinians, according to wintesses.
The unit ambushed his car at a roundabout and several shots were fired into the vehicle.
