Two policemen and an 11-year-old girl have been injured in a roadside bomb blast in the north-western Pakistani city of Peshawar, police say.
The remote-controlled device targeted a police station chief who was travelling through the Rashidabad area, a police official told the AFP news agency.
The police chief survived the attack, though his car was damaged.
A spate of bomb attacks in and around the city of Peshawar in recent weeks have killed hundreds of people.
Attacks across Pakistan have dramatically increased as the army continues its offensive against the Taliban in the South Waziristan region.
A senior police official said that the police station chief was driving to his office in his private car when the bomb went off.
An 11-year-old girl, the official and his guard were injured, police said. Eyewitnesses said the car was damaged and its windshield smashed.
The city has been frequently targeted by militants in recent weeks.
Earlier this month, a suicide car bomb attack on Pakistan's main intelligence agency in the city killed at least 12 people and injured 40.
And more than 100 people were killed in a blast at a market in Peshawar last month.
