Raipur, Nov 12 Defying Maoist threats, over 70 per cent voted on Monday in 18 Maoist-affected Assembly constituencies of Chhattisgarh in the first phase, marking the start of five-state elections dubbed the 'semi-final' before the Lok Sabha battle next year.
The Election Commission said the final figure would be higher as data was still being collated.
"Over 70 per cent voters cast their vote... The final figure may touch the last election's figure of 75 per cent as data is still being obtained," Senior Deputy Election Commissioner Umesh Sinha told the media here.
The Maoists, who had warned citizens against taking part in the poll process, detonated an Improvised Explosive Device (IED) in Katekalyan in Dantewada district, minutes before the voting began, narrowly missing a foot patrol of the Central Reserve Police Force (CRPF).
