Seventy five Indian police officers have died in a series of ambushes by Maoist rebels.
Security convoys on patrol in dense jungle in central India came under fire from rebel fighters concealed in the surrounding hilltops.
Army helicopters had to be called in to evacuate the wounded after the insurgents also attacked rescue teams.
Raman Singh, the Chief Minister of Chhattisgarh State, said: “We are discussing how to send reinforcements to the injured personnel of the Central Reserve Police Force to help them, and how to better use the air support.”
The security forces recently launched a major offensive against the Maoist rebels in their stronghold.
Nearly 50,000 federal paramilitary troops and tens of thousands of police officers are involved in the operation.
The debacle will pose questions about exactly how well prepared the Indian military is to take on the insurgents.
