In a statement, the military's media affairs wing said that security forces conducted an operation after receiving information about the presence of terrorists in the area.
During the exchange of fire, Captain Sikander — who was 27-years-old and hailed from Pakpattan — was martyred, the statement said.
"TTP terrorist commander Khawaza din alias Sher Khan was killed. Weapons and ammunition [were] recovered from the hideout," the statement added.
The ISPR said security forces conducted the operation after receiving information that terrorists were present at a hideout in the area.
During intense exchange of fire, 10 terrorists, including four commanders, were killed, it said, adding that weapons and a large quantity of ammunition were also recovered.
"All the killed terrorists remained actively involved in planting IEDs (improvised explosive devices), conducting fire raids, and target killing of innocent civilians. These terrorists were planning to conduct more acts of terrorism inside the South Waziristan district," the statement had said.
In a separate incident that occurred the same day, a Frontier Corps (FC) soldier was martyred and another injured after terrorists targeted a check post from across the Iran border.
