One jawan was killed as the Maoists attacked the Chhattisgarh Armed Forces camp in Narayanpur.
Union Home Minister Rajnath Singh had earlier urged the Maoists to drop their weapons and come back to the mainstream.
Maoists, also known as 'Naxals' in India, seek the violent overthrow of the Indian state and have fought authorities for decades, particularly in rural areas of central and eastern India where they enjoy some support.
