Perks of penance for Saudi jihadis

In a small compound on the outskirts of Riyadh, the Saudi government is exploring new ways to combat extremism.
This is still a prison, run by the Ministry of Interior and housed inside secure premises with high perimeter walls and barbed wire, but the Saudi authorities prefer to call it a "care centre" and refer to prisoners as "beneficiaries".
This is not what you would imagine when you think of a typical Saudi jail.
Inside, prisoners enjoy access to wide-ranging recreational facilities including their own swimming pools, video games and table tennis.
In return for the more relaxed environment, prisoners have to attend religious education classes where Islamic scholars challenge their views.
The thinking behind the new initiative is to fight al-Qaeda's ideology by convincing militant Islamists they have a distorted view of Islam.
The Ministry of Interior oversees the new scheme and has created the Ideological Security Unit (ISU) dedicated to co-ordinating their efforts.
"You cannot defeat an ideology by force. You have to fight ideas with ideas," says Abdul-Rahman Hadlaq, ISU director.
But the centre goes beyond just debating ideas. It also encourages prisoners to express their "softer side" by running art therapy classes where inmates find alternative ways to express themselves.
