Pakistan's military has launched air strikes against suspected militant hideouts near the Afghan border.
It's the first aerial operation against Taliban insurgents in two months.
The Pakistani Army said the strikes were in response to a number of recent attacks against police and civilians in Islamabad and Peshawar.
In the most recent incidents, at least seven people were killed in attacks in northwestern Pakistan on April 22.
Reuters quotes a senior military official in Peshawar as saying Pakistani ground forces began operations in the area early on April 24 following the air strikes.
Another military official said at least 15 militants were killed, but there was no official confirmation of this figure.
The Pakistani Taliban formally ended a 40-day cease-fire last week, but efforts to resume peace talks continue.
