Suicide bombing kills at least 20 in Pakistan
The attack appeared to be the work of two suicide bombers, police said.
"Many of the people are badly wounded and the death toll could be much higher," police official Zia Ullah said.
Militants have killed hundreds of pro-government tribal leaders in the northwest, as well as shown they can hit the military not only at camps and posts in the provinces, but at its very heart with attacks on the army's headquarters and its powerful spy agency in the city of Rawalpindi.
The killing of Osama bin Laden in Pakistan earlier this month is thought unlikely to weaken the Pakistan Taliban, while the United States has stepped up drone attacks on militants since bin Laden's death.
