Jihadist Islamic State (EI) has threatened to attack Saudi prisons to free their prisoners, in response to the execution of dozens of militants on Saturday in Saudi Arabia, calling it "blackmail".
"The Saudis tyrants with this action demonstrated its new policy, which is to concentrate the monotheistic (in reference to supporters of EI) in prisons and turning them into hostages," according to the editorial of the weekly Al Naba, published online by the EI .
The jihadists claimed that in this way the Saudi authorities will "respond to any threat from the mujahideen (holy warriors) with the execution of the hostages."
The editorial said that to free their prisoners the way is "overthrow regimes that stop and then destroy their prisons."
In this sense, the terrorist group threatened to destroy the prisons of Al Hayer, about 25 kilometers south of Riyadh, and Al Tarfiya, located in the city of Buraydah, where most prisoners are convicted of terrorism .
Al Hayer, one of the largest prisons in Saudi Arabia, with high levels of security, last July was the target of a suicide attack claimed by the EI.
Saudi authorities executed last day 2-47 people, mostly Sunni militants sentenced to death for involvement in attacks in the kingdom in 2004 and 2005.
The EI previously said it would release the prisoners, while threatened Saudi Arabia, calling perpetrate attacks against the ruling Al Saud family, security forces and Shiite.
