Preliminary charges against the former leader of guerrilla group Ansar al-Islam were filed as long ago as October 30, two full months before he was arrested last Friday. The filing initially was connected to Krekar's alleged involvement with two suicide bombings in Northern Iraq.

It also allowed investigators to monitor Krekar's subsequent Internet use, and charges were widened after Krekar reportedly claimed online that suicide bombers carry out jihad, or holy war.

Krekar's defense attorney denies Krekar has done anything wrong. "He has only answered questions and held a speech about such things as suicide bombing and jihad," lawyer Brynjar Meling told newspaper Dagsavisen.

Meling said he has no worries about Krekar's Internet usage, and he was working to get Krekar released on Monday.

Prosecutor Erling Grimstad said he would immediately appeal if an Oslo city court releases Krekar from custody Monday afternoon.
