Militants have detonated a car bomb near a police building in northwest Pakistan.
Police Wednesday said at least 15 people were wounded in the dawn attack in the city of Peshawar, near the Afghan border.
No group immediately claimed responsibility for the blast. But a string of attacks in Pakistan has followed the U.S. raid that killed Osama bin Laden.
The Pakistani Taliban vowed revenge and already has claimed three attacks since the raid on May 2.
