At least one person has been killed and 10 others wounded after a pre-dawn rocket attack in the Pakistani city of Peshawar, police say.
A senior police official said around a dozen rockets had landed in the city early on Tuesday.
Panicking residents ran out of their homes, and the office of a paramilitary force was hit, the police said.
Peshawar is the main city near the Swat valley, where an offensive was recently waged against the Taliban.
Nobody claimed responsibility for the rocket attacks, which are rare in Pakistan's cities.
"It is an act of terrorism, but we don't know who the attackers are," local police official Nisar Khan told the Associated Press news agency.
He said a headquarters of the paramilitary Frontier Corps was damaged in the attack, but no-one was injured.
The capital of North West Frontier Province, Peshawar has become the front line city in Pakistan's campaign against militants.
Bombings and suicide attacks coupled with kidnap for ransom have become commonplace.
In June, the city's luxury Pearl Continental hotel was hit by a suicide bombing which left at least 18 people dead including two UN staff.
