An explosion ripped through a crowded bus stand in Pakistan's north-western district of Swat on Thursday, killing two people injuring at least 15, police said.
The bombing took place in Mingora, the main city of the mountainous district, where the military has been fighting Taliban militants since March 2009, DPA reported.
"According to the initial reports we have received, two people are dead and 15 people are injured," an official at the city's police control room said, adding that the casualty figure could be much higher.
"Eight vehicles are also damaged in the blast," the official said.
The nature of the blast was not known yet.
Swat is located some 140 kilometers north-west of Islamabad in the militancy-plagued Khyber-Pakhtunkhwa province.
