Pakistani security forces have killed at least four terrorists during an intelligence-based operation in the South Asian country's North Waziristan district, media reports said on Wednesday.

According to the Inter-Services Public Relations (ISPR), security forces conducted an intelligence-based operation (IBO) on Tuesday night in the Spinwam area of North Waziristan “on the reported presence of khwarij”, reported Dawn News.

“During [the] conduct of the operation, own troops effectively engaged khwarij’s location, and after an intense exchange of fire, four khwarij were sent to hell,” the statement said.

Security forces recovered weapons from the terrorists.

Security forces later conducted a sanitisation process to eliminate any other terrorists located in the region.

Pakistan has been witnessing a spike in terror activities in recent months.
