Authorities in California say a man in a wheelchair detonated a pipe bomb inside the waiting room of an east Oakland health clinic on Tuesday night, taking his own life in what is believed to be a suicide bombing, though not necessarily with the intent to kill others. “At this time it doesn’t appear to be related to terrorism,” Oakland police Lt. Rachael Van Sloten said, according to the San Francisco Chronicle.

The Oakland Police Department released the following statement regarding the incident: Witnesses reported that an adult male, who was in a wheelchair, entered the lobby of the clinic armed with what appeared to be a pipe bomb and detonated the bomb taking his own life. No other injuries were reported. FULL REPORT
