India's Prime Minister Manmohan Singh says his country is losing the battle against Maoist rebels.
Mr Singh told a meeting of police chiefs from different states that rebel violence was increasing and the Maoists' appeal was growing.
The rebels say they are fighting for the rights of the poor.
They operate in a large swathe of territory across central India, and in some areas have almost replaced the local government.
More than 6,000 people have been killed during their 20-year fight for a communist state.
