PESHAWAR: A US drone strike killed four suspected terrorists, including a key militant commander, in the Lalpura area of Afghanistan's Nangarhar province.

Security sources say the drone targeted a double-cabin van, killing four men on the Afghan side of the porous Pak-Afghan border, adjacent to Pakistan's Khyber tribal region. The militant commander was identified as Habibullah.

The details could not be independently verified. Tracking of drone strikes in Afghanistan is patchy since many of them take place in remote regions and are not reported
