At least 20 Palestinians were detained in pre-dawn Israeli raids across the occupied West Bank, Al Jazeera reports.

Many of those detained were workers from Gaza who were staying in the Palestinian village of Barta’a, west of Jenin, and the separation barrier.

Close to dawn, Israeli forces raided the refugee camp of Balata, east of Nablus. Residents said Israeli forces were seen mapping roads and filming several areas in the camp.

Other raids targeted Qusra and Burqa villages near Nablus as well as Qalqilya and Beit Ummar town north of Hebron.
