According to Harnai Deputy Commissioner Hazrat Wali Kakar, the blast occurred when an improvised explosive device (IED) detonated in Coal Mines Area PMDC 94 in Harnai’s Shahrag district.

“The bodies of the deceased and the injured have been shifted to the Shahrag Basic Health Unit,” Kakar said.

No group has claimed the attack.

Evidence was being collected, and a preliminary investigation showed that the explosive material was planted on the roadside, the statement added.

Maqsood Ahmad, uncle of the blast victim Iqbal Hussain, told Dawn.com that only men in the family knew about the latter’s demise and were keeping the incident hidden from the rest of the family till the body arrived in Shangla, Lilownai.

He said Hussain had gone to work two months ago and was a hardworking man struggling to earn income for his family back in Shangla.
