The attack occurred at the al-Ghazl market in Baghdad on Feb 1. There were two bombs, both carried by mentally handicapped women. The bombs were detonated remotely, killing more than 40 and wounding more than 80.

On Sunday, US and Iraqi forces arrested a man suspected of working with al Qaeda to supply them with the two women. He’s the director of a Baghdad psychiatric hospital.

The acting director of a Baghdad psychiatric hospital has been arrested on suspicion of supplying al-Qaeda in Iraq with the mentally impaired women that it used to blow up two crowded animal markets in the city on February 1, killing about 100 people.

Iraqi security forces and US soldiers arrested the man at al-Rashad hospital in east Baghdad on Sunday. They then spent three hours searching his office and removing records. Sources told The Times that the two women bombers had been treated at the hospital in the past.

“They [the security forces] arrested the acting director, accusing him of working with al-Qaeda and recruiting mentally ill women and using them in suicide bombing operations,” a hospital official said.

Why mentally ill bombers? Well…

The attraction of mentally impaired women to al-Qaeda was obvious, he said. Being women they could get close to targets with less chance of being stopped or searched; being mentally impaired, they were “less likely to make a rational judgment about what they are being asked to do”…

An insight into the way al-Qaeda thinks came in a letter written by one of its leaders in Anbar province that the US military seized in November and released in part on Sunday. “It is possible to use doctors working in private hospitals and where the infidels/ apostates are treated who have serious conditions to be injected with [air bubbles] that will kill them,” it said.

Words fail me.
