Well, AP looks like they’ve just put up a bit more info on the Ansar al-Islam guy:
http://www.usatoday.com/news/world/iraq/2004-02-07-iraq_x.htm "Elsewhere, U.S.-allied Kurdish forces in northern Iraq captured a suspected member of Ansar al-Islam, a radical Muslim group, as he tried to enter the country from Iran, an Iraqi official said."
"U.S. and Kurdish officials believe Ansar al-Islam is linked to al-Qaeda and may have been behind last weekend's twin suicide bombings in the northern city of Irbil. . . ."
"The alleged Ansar al-Islam member, Warzir Ali Wali Mamoyi, was arrested Thursday at a checkpoint in Kurdish-controlled Sulaimaniyah province, according to Omar Ghareeb, a local civil administration official."
"He described Mamoyi as a member of a committee that issues policy statements for Ansar al-Islam, a mostly Kurdish militant group that follows a strict interpretation of Islam."
"Kurdish officials believe Ansar al-Islam carried out the Sunday suicide bombings at the offices of the Kurdistan Democratic Party and the Patriotic Union of Kurdistan in Irbil. Another group, the Ansar al-Sunna Army, claimed responsibility for the attacks, which killed 109 people, in a statement posted on a Web site. U.S. officers believe Ansar al-Sunna is a splinter group of Ansar al-Islam."
"A Kurdish newspaper, Kurdistani Nuwe, said Friday that Mamoyi was planning to travel to the Sunni Triangle area, possibly to link up with anti-U.S. insurgents from the former regime of Saddam Hussein."
