As voting for the first phase of the Chhattisgarh Assembly elections began in 18 constituencies amid tight security on Monday, Maoists resorted to blasting improvised explosive devices aiming to halt the polling process in the state.

10.7 per cent voter turnout was recorded till 10 am in the first phase of polling. Voting for 10 seats began at 7 am and will end at 3 pm, while that in the remaining eight seats began at 8 am and will continue till 5 pm.

All the 18 constituencies are known as Maoist hubs.

Maoists triggered an IED blast in Nayanar village of Katekalyan area in Dantewada at around 5:30 am to target the security forces. The blast occurred when troops of the 195 Battalion of CRPF were approaching a polling booth. No injury to troops was reported.

Later, three IEDs were detected near a polling booth in Konta’s Banda area in Maoist-affected Sukma. Voters were immediately shifted to a makeshift polling booth established under a tree, away from the actual polling booth.

The CRPF bomb disposal squad is in the process of defusing the explosive devices.
