Isil’s top bomb secrets revealed

Trap doors in floorboards and bottles of alcohol on back seats – Iraq’s intelligence service on Monday detailed how the Islamic State in Iraq and the Levant’s (Isil) car bomb cell eluded the police for months.

The suspected leader of the group was arrested riding a bicycle in an upmarket neighbourhood, a spokesman for the Iraqi national intelligence service told AFP.

Fahim al-Atraqchi said: “When we first picked up a scent in our hunt for this network, we organised surveillance that lasted six months.

“Then we set up a task force and arrested all of them in 72 hours.”
