Al-Qaeda's so-called "oil minister" in Iraq has been arrested along with 10 other members of the group, the interior ministry said on Saturday. "The police in Diyala province arrested eleven members of the Islamic State in Iraq (Al-Qaeda's self-styled name there), including Ali Mahmud Mohammed. He is the oil minister of this organisation," the statement said. The ministry did not say when he was detained, only that he was arrested north of Baquba, the capital of Diyala province and one of the most unstable parts of the country. Mohammed was known for his involvement in hijacking tanker shipments of crude oil and petrol for Al-Qaeda and abducting the drivers. On February 21, Al-Qaeda's so-called "irrigation minister" and "finance minister" were also arrested.
