A Central Industrial Security Force jawan and three civilians were killed after Maoists attacked a bus of the security forces at Dantewada in poll-bound Chhattisgarh on Thursday.
The bus, deployed for poll duty, was blown up at Bacheli in the Naxal-hit district. This is the second attack in 10 days.
On October 30, Naxals had attacked a Doordarshan crew in Dantewada. The cameraman was killed in the attack.
