A landmine blast blamed on Maoist rebels killed seven police officers on Sunday in an insurgency-hit region of central India, the latest deadly attack during national elections, an official said.
Police said the blast took place when their vehicle was moving along the Murmuri-Chamuri area of the district – a stronghold of Maoist rebels.
The attack comes two days after the police arrested a university professor GN Saibaba from the country\’s capital, New Delhi, on charges of links with Maoist rebels.
Rebels, who claim to be fighting for India\’s poor and tribals, control large areas of what officials call "red corridor" stretching from northeast to central India.
They have been fighting for more than 40 years claiming they have been inspired by the Chinese revolutionary leader Mao Zedong.
India\’s Prime Minister Manmohan Singh has called Maoists the country\’s greatest internal security threat.
