Pakistani police say a suicide car bombing killed at least 11 people,
including three children, in the latest attack in the northwestern city
Officials say the bomber was waiting in a line of cars at a security checkpoint just outside the city Saturday, when he detonated the explosives.
Authorities say the blast also killed two police officers, wounded at least 20 people, and destroyed several cars.
The bombing came a day after a suicide bomber struck the Peshawar office of Pakistan's Inter-Services Intelligence agency, killing 10 people. That blast caused a large portion of the three-story ISI building to collapse.
Authorities say recent militant attacks in Peshawar are in retaliation for the government's offensive against the Taliban in the tribal regions bordering Afghanistan.
Elsewhere Saturday, the Pakistani military says troops killed eight militants in the latest fighting in the northwest Swat Valley.
