Israeli police units yesterday raided the cells of Palestinian detainees in the Megiddo prison, near the city of Umm Al-Fahm, the PLO's Prisoners and Ex-Prisoners Commission said.
According to the organisation, the occupation's police inspected and vandalised the belongings of the detainees.
Hasan Abed Rabbo, a spokesman for the commission, said: "The Israeli repression forces attacked the rooms of the Palestinian prisoners while the prisoners were inside and destroyed and sabotaged their belongings."
Tensions in the Israeli prisons, where Palestinian political prisoners are held, have increased since 6 September when six prisoners escaped from Gilboa Prison through a tunnel. All of the six escapees were recaptured days later.
According to recent statistics, more than 4,500 Palestinian and Arab prisoners are being held inside the Israeli prisons for resisting the Israeli occupation of Palestine.
In recent years, Palestinian prisoners in Israeli detention have launched multiple protests to demand better conditions, including an end to the unjustified Israeli policy of raiding prisoners' cells.
