PESHAWAR – At least four suspected militants were killed on Sunday in a US drone strike in Nazyan district of Afghanistan’s Nangarhar province, near Pakistan’s Khyber Agency.

The drone strike targeted a militant compound in the Nazyan district, killing four suspected militants including Taliban leader Umar Naray, sources said.

Militants based in the Nazyan district had reportedly planned the devastating attack on the Army Public School in Peshawar, which left over 140 children and teachers dead and scores injured.

Pakistani security forces also carried out ground offensives in Khyber Agency, particularly the Tirah Valley of Bara which borders Nazyan.

Till 2014, the Nazyan district had reportedly been serving as a safe haven for the Mullah Fazllullah led Tehreek-i-Taliban Pakistan (TTP).
