An Afghanistan military helicopter on Tuesday struck a group of militant mine planters in the southern province of Kandahar and killed four of them, Nisar Hand, an Afghan security official said.
Hand said that the four militants were going to plant mine under a bridge in Dand district of Kandahar province in the wee hours of Tuesday.
Acting on tip-off, he said, a gunship aircraft was deployed in the area and killed them on the spot.
He, however, did not provide further details about the airstrike.
Kandahar, the birthplace of Taliban militants, has been the scene of increasing insurgency over the past couple of months.
