The 4 September 2007 Rawalpindi bombings refer to the incident on 4 September 2007 in which suicide bombers attacked a bus carrying government workers in a commercial district of Rawalpindi. Twenty-five people were killed and 68 injured. Police increased security in the nearby Pakistani capital of Islamabad.
The bombs exploded after 7:20 am near the army General Headquarters and other top military sites. One attack was aimed at a Defence Ministry bus picking up army staff passengers and an explosives-laden motorcycle caused the second attack, near a market.
At 7:20 am, the front of a bus carrying army staff passengers exploded, blowing off the vehicle's roof and destroying all but the rearmost seats. Although Interior Ministry spokesman Javed Iqbal Cheema referred to the attack as a suicide bombing, a local police officer stated the bomb might have been previously planted.
Approximately fifteen minutes after the first blast, a suicide bomber crashed a motorcycle into nearby vehicles, killing at least one colonel.
Preliminary investigations concerning the September 2007 bombings in Rawalpindi note that the Taliban figure Baitullah Mehsud is the primary suspect behind the attacks.
