The suspected leader of an Al Qaeda-linked militant network was captured Thursday by Iraqi military forces, security officials said, in what could mark a significant blow against Sunni insurgents as they step up attacks. Two separate homicide bombings, meanwhile, killed at least 42 people.

Abu Omar al-Baghdadi has been a key target for U.S. and Iraqi forces for years as the leader of the Islamic State of Iraq, an umbrella group of Sunni militant factions that is believed dominated by Al Qaeda in Iraq.

But little is known about his origins or real influence over insurgent groups, which have staged a series of high-profile attacks in recent weeks, including, apparently, the two homicide blasts Thursday in Baghdad and north of the capital in Diyala province.

The U.S. military has even said al-Baghdadi could be a fictitious character used to give an Iraqi face to an organization dominated by foreign Al Qaeda fighters.

But Iraqi security forces said he was in custody.

Iraqi state television quoted military spokesman Maj. Gen. Qassim al-Moussawi as saying al-Baghdadi was arrested in Baghdad. Security officials also told The Associated Press that he was captured. The officials spoke on condition of anonymity because they were not allowed to release the information.
