More Raids In Nairobi

Nearly two dozen FBI agents and Kenyan police raided a house Thursday afternoon in a gated and guarded Nairobi suburb. Neighbors say the men who lived there worked for an aid agency called Al-Ibrahim.

The search lasted six hours. No bomb-making materials were found, only papers. Most of them in Arabic, reports CBS News Correspondent Vicky Mabrey.

Investigators won't say what led them to the house or what they were searching for, or whether it's connected to yesterday's raid on a run-down hotel in the center of Nairobi.

There agents seized the hotel logs and scoured two rooms where four Middle Eastern men were registered for the three days prior to the August 7 bombings.

While investigators won't say what's driving these raids, at least part of their information is coming from a suspect they've been questioning for the last week. CBS News has learned from sources here in Nairobi that Mohammad Saddiq Odeh has confessed his part in the bombing to FBI investigators and has named accomplices.

Odeh also has admitted to being an associate of Osama bin Laden and says he was trying to get back to Afghanistan when he was arrested.
