At least 10 people have been killed and 55 wounded in a suicide car bomb attack on an office used by Pakistan's main intelligence agency in the northwest city of Peshawar.
A military spokesman said the bomber's target was the office of the Inter-Services Intelligence (ISI) agency.
The blast brought down the front of the three-storey building and sent a thick column of smoke billowing over the city.
It has been reported that the bomber was in a type of vehicle that usually delivers medical supplies.
Shortly after the Peshawar attack, a suicide car bomber attacked a police station near the northwestern town of Bannu, killing three policemen and wounding eight.
Security is tight across the country with numerous checks on roads and it was not clear how the bomber was able to approach the ISI office.
Militants who attacked army headquarters in Rawalpindi last month were dressed in army uniforms and travelled in a vehicle with military markings, reflecting an increasing sophistication in their attacks.
