On 28 May 2009 four bombs were detonated in Peshawar, killing at least 10 people and injuring more than 70 others as militants targeted a busy market and a military checkpoint within the city. The bombings occurred in two separate attacks that were spaced hours after each other. The Taliban had previously warned of more attacks, following a bombing at a police station in Lahore, perpetrated less than 24 hours before the Peshawar attacks. According to reports, in the first attack explosives-laden motorcycles were detonated via timer, and as police officers arrived at the scene they were met by a Taliban ambush. The second attack occurred when a suicide bomber drove his car into a checkpoint on the outskirts of Peshawar. Pakistani officials have banned all public gatherings in the city and have placed restrictions on motorists in order to prevent additional attacks. The coordination of the attacks and the fact that they occurred only 24 hours after the Lahore incident raises some concern that a new wave of Taliban attacks may be launched against Pakistani cities.
