Taliban attacks in northwest Pakistan killed on Saturday at least 16 people, police said.
The blast destroyed the building and nearby houses and shook the town of Bannu, in the tribal North West Frontier Province.
"Six bodies have been recovered. One is policeman, one is a person detained at the police station while four bodies have not yet been identified," Aurangzeb Khan, an official at the town's police control room, told Reuters.
He said 30 people, most of them policemen, were wounded.
Shortly afterwards, a bomb planted in a car went off in the carpark of a commercial building close to a military hospital in the provincial capital of Peshawar, killing at least six people.
"The frontside of the building has collapsed. Over two dozen cars have been destroyed," a Reuters witness said.
Qari Hussain, a Taliban commander, called Reuters by telephone to take responsibility for the attack and warned of more to come.
"The government was taking undue advantage of our silence. We will carry out more such attacks and these will be much more powerful," Hussain said, introducing himself as top spokesman of Pakistani Taliban chief, Hakimullah Mehsud.
Hakimullah was appointed chief of Tehrik-e-Taliban Pakistan, or Taliban movement of Pakistan, a loose alliance of around 13 armed groups, after the death of his predecessor, Baitullah Mehsud, in a U.S. missile strike by a pilotless drone in South Waziristan on the Afghan border in August.
Thirty-three people were killed in a car-bomb suicide attack near the garrison town of Kohat this month.
