Maharashtra Chief Minister Devendra Fadnavis and Home Minister Rajnath Singh also condemned the attack in a Twitter post.
The Maoist insurgents, known as Naxals, have battled the state for decades, saying they are fighting for people left out of a long economic boom in Asia's third-largest economy.
Security forces killed at least 37 Maoist militants last year in Gadchiroli, the same district where Wednesday's attack took place.
