Pakistan's foreign ministry had reported in April that in the past few days, incidents along Pak-Afghan border had significantly increased, wherein, Pakistani security forces were being targeted from across the border.

It said seven Pakistani soldiers were killed in the border area of North Waziristan on Thursday. North Waziristan borders the eastern Afghan province of Khost, where the strikes are said to have taken place in April.
