PARACHINAR: Six militants were killed during a clash with security forces in the Kurram tribal region on Wednesday, DawnNews reported.

The militants were killed in the tribal region's Marghan area.

A military offensive was launched against militants in the central tehsil of the tribal region on Sunday and families had started fleeing the conflict zone.

At least 400 families in central Kurram, where the operation is focused, managed to leave the area and registered with a government-run camp in lower Kurram, a government official said.

The official had estimated that thousands of families might have left the region, but many of them opted to stay with relatives rather than go to the camp.
