At least 10 people were killed and several others injured in two separate explosions in a densely populated area of Parachinar in Kurram Agency on Friday.
The explosions were reported to have occurred near a market at a bus stop, according to Dawn News.
Rescue operations are underway. An emergency has been imposed in hospitals in the area, and the injured are being taken to the District General Hospital in Parachinar.
Security forces have cordoned off the affected site and are conducting a search operation.
Kurram is the only Shia Muslim region in a predominantly Sunni country. Sunni hardliners, currently operating through different Taliban factions including the Islamic State group, consider them heretics and have often targeted them.
In a deadly bombing in March this year, a blast outside an Imambargah located in a busy Parachinar market claimed the lives of 24 people and left 90 others injured
