PESHAWAR: At least four mortar shells were fired across the border from Afghanistan on Wednesday, injuring three people in Pakistan’s troubled tribal region of North Waziristan, security officials said.

According the officials, the shells hit a residential compound located in Hasan Khel village, around 30 kilometres east of Miranshah, the main town in North Waziristan tribal region.

Three people were reported to have been injured in the incident.

Both Pakistan and Afghanistan have accused each other in the past of repeated shelling barrages across the poorly policed border.

A senior Afghan army general visited Pakistan earlier this month to discuss the issue of cross-border shelling, which has soured relations between the two neighbours.

The two countries share a common 2,400-kilometre mountainous border, and Taliban and other al Qaeda-linked militants are known to have carved out strongholds on either side.
