An explosion has ripped through a busy marketplace in the northwestern Pakistani town of Kalaya, killing at least 26 people, officials said.
More than 55 people were wounded when the blast occurred on Friday morning, health official Adnan Tahir told Al Jazeera by telephone from the provincial capital, Peshawar.
It was unclear whether the explosion was caused by a suicide bomber or an improvised explosive device, local government official Mudassir Bangash told Al Jazeera.
"Reports are still coming in, nothing is confirmed yet," Bangash told Al Jazeera by telephone.
