Sukma, April 4 (ANI): An official from India's paramilitary Central Reserve Police Force (CRPF) was severely injured on Monday in an attack by Maoists in insurgency-hit Sukma district of Chhattisgarh. The injured, Sub-Inspector Mahendra Singh, was then admitted to a hospital in Jagdalpur city in Chhattisgarh. The rebels opened indiscriminate fire at security officials but fled the spot when security forces retaliated. Maoists are rebels who try to sink deep roots and form links after decades of neglect. The Maoists, also known as Naxals, have killed police and politicians, and targeted government buildings and railway tracks in an insurgency that has killed thousands since the 1960s.
