Palestinians clashed with security forces on Saturday over the death of Arafat Jaradat, a prisoner in Megiddo prison who died of cardiac arrest, Israel Radio reported.
Palestinian officials demanded an international investigation into the death, saying Jaradat died during investigation and claiming he was tortured.
Dozens of Palestinians hurled stones at IDF soldiers in Hebron. Soldiers responded by using means of crowd dispersal.
In Ofer prison, inmates rioted, throwing objects and pounding on doors. 3,000 Palestinian prisoners in Israeli prison said they will hold a one-day hunger strike on Sunday in solidarity with Jaradat.
