A blast caused by what the FBI called "a destructive device" rocked a Bloomington Islamic center at dawn Saturday, just as a small group of worshipers had gathered for the day's first round of prayers.

No one was hurt in the explosion, which heavily damaged an imam's office at the Dar Al Farooq Center and sent smoke wafting through the large building. Windows in the office were shattered, either by the blast or possibly by an object thrown through them.

The blast was reported at 5:05 a.m., a time when 15 to 20 people are usually gathered at the center for morning prayers, and awoke many residents of the neighborhood. Congregants and neighbors expressed relief that no one was hurt, but also reacted with shock and dismay.
