Naxals ambush CRPF camp in Bijapur, 4 jawans killed

Four CRPF jawans were killed in an ambush by naxals in poll-bound Chhattisgarh's Bijapur district. The ultras triggered a powerful land mine blast about 1km away from a CRPF camp when a vehicle carrying personnel was on its way back. The attack comes as Chief Minister Raman Singh launched the BJP's campaign for the first phase of polls in the neighbouring Sukma district.
