The health of TRS leader K Chandrasekhar Rao is deteriorating due to his fast-unto-death but he is refusing medical treatment, a senior government official has said.

"Doctors, who came from Hyderabad, have examined him. They said he needs medical treatment immediately. He has not taken any food and is not cooperating. He is refusing treatment," Khammam district collector Usha Rani told reporters at Khammam Tuesday night.
