Indian home minister Rajnath Singh expressed grief over the killing of policemen in the attack and said his ministry was in touch with Maharashtra local government.
“We are providing all assistance needed by the state government. Ministry of home affairs is in constant touch with the state administration,” Singh in a statement said.
Local media reports said the attack was seen as revenge for the gunfights conducted by the commando unit in the region last year in which 40 Naxal cadres were killed.
The Naxals were in the final stages of observing a week-long protest to mark the first anniversary of 40 of their slain cadres.
Maharashtra Police Chief Subodh Jaiswal while addressing media said they were fully prepared to give a befitting reply to the Wednesday’s attack.
The attack comes hours after Naxals torched 25 vehicles at a road construction site in the Gadchiroli district.
Naxal insurgency has its genesis in the violent left-wing rebellion that began in 1967 at village Naxalbari in Indian state of West Bengal.
Currently Naxals are active in more than a third of India’s 600-odd districts across central and eastern part.
India’s former prime minister Manmohan Singh once termed the Naxalite movement as India’s “greatest internal security challenge”.
New Delhi has deployed several companies of its paramilitary forces to take on Naxals in their strongholds.
The insurgency reportedly has claimed more than 6,000 lives and rendered thousands of poor inhabitants homeless.
In 2010, at least 76 men of Central Reserve Police Force (CRPF) were killed in Dantewada district of Chhattisgarh, the deadliest attack so far.
