Briefing mediapersons on Thursday, the IG said a number of developmental works is underway in the region due to which sanitising the area is important for strengthening security.
Militants yesterday evening shot dead a CRPF jawan Mukhtar Ahmad Dohi, who was on leave, near his residence at Check Chotipora in Shopian in south Kashmir.
The injured personnel were shifted to a hospital here, where constable Mritunjoy of 115 battalion succumbed on Thursday, an official said.
While the CRPF team was cordoning off a patch of jungle near Chintabegu village, Naxals triggered the blast of an improvised explosive device.
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.
CRPF said that a video clip showing some youths beating its jawans was authentic and that it has started investigation.
