This is the latest blast in a series of attacks that have hit Pakistan in recent days.

Officials say at least 15 people were killed and 25 are injured. Three policemen were among the dead.

The blast destroyed several vehicles and knocked over market stalls.

The court complex is across the road from the city's top hotel.

The hotel was attacked by a suicide car bomber back in June.

And only last week a security agency building on the same road was bombed.

Taliban militants have stepped up the attacks since the Pakistani army began an offensive against them last month.
