National Security Minister Itamar Ben-Gvir "wants to execute Palestinian security prisoners," Hamas representative for jailed Palestinians Zaher Jabarin claimed on Monday.
"The occupation is committing heinous crimes against prisoners in jails, and Ben-Gvir has included plans to execute prisoners, there is a real massacre in prisons," Jabarin said.
Jabarin, a former prisoner released as part of the 2011 deal for Gilad Schalit, claimed that four prisoners were killed by "torture and daily attacks."
Earlier on Monday, a Palestinian security prisoner in Megiddo Prison died on Monday after feeling unwell, the Israel Prison Service announced. The prisoner, 33 years old from the West Bank, was imprisoned in February.
