Islamabad: At least 15 people were killed on Sunday in a bomb blast in a cantonment in tribal region of Pakistan, the media reported.
According to hospital authorities, 47 people were injured in the blast, Dawn reported.
The explosion was carried out in the bustling Sadar market of Parachinar cantonment in Khurram Valley, an official said.
Security sources said two suspects have been taken into custody from the blast site.
The injured were shifted to a nearby hospital where as many as 15 people were in serious condition, the official said.
No militant group has claimed responsibility for the attack yet.
Khurram is one of the most sensitive tribal areas as it borders three Afghanistan provinces and at one point was one of the key routes for militant movement across the border.
The agency is adjacent to North Waziristan where Operation Zarb-i-Azb is in progress against the Tehreek-i-Taliban and other insurgent groups.
Parachinar is the administrative headquarters of the agency near the Afghan border.
It is small garrison town developed by the British army in the foothills of Spin Ghar (White Mountain) in mid-1895.
