A security prisoner stabbed a warden in the head Friday during an inspection of his cell at the Eshel prison. Despite his wounds, the warden managed to overpower the prisoner, who was then sent to solitary confinement. The officer was treated for his wounds. The prisoner, Muhammad Halil abu-Alba from the Islamic Jihad, was sentenced to eight consecutive life sentences on charges of running over and killing seven soldiers and wounding 21 others in 2001 at the Azur intersection. Prisoner authority officials immediately launched an investigation to determine the motive behind the attack, and suspended privileges of prisoners in the wing. They also increased cell inspections.
