Twenty-two jawans were killed in the Maoist ambush in the inhospitable terrain of an edgy district of Bijapur, south Chhattisgarh, on Saturday.
As many as nine CRPF personnel were killed and three others critically injured when Maoists blew up a mine protected vehicle at Kistaram in the strife-torn Sukma district.
The Maoists reportedly used few under-barrel grenade launchers, a sophisticated weapon used by security forces, to inflict fatal casualties on the troops by lobbing grenades in quick succession.
