NEW DELHI, May 24 (Xinhua) -- At least one Indian security forces personnel was killed and one more injured in a blast triggered by left-wing Naxalite rebels in the central state of Chhattisgarh on Thursday, police said.
The deadly attack on the para-military Central Reserve Police Force (CRPF) took place at Puswada village in the state's Sukma district while they were on a routine combing operation.
"One official of the CRPF was killed and one constable was injured in the attack. The injured security personnel has been sent to state capital Raipur for further treatment," Inspector General of Chhattisgarh Police Vivekanand Sinhna told the media.
Chhattisgarh is often hit by Naxalite violence.
The rebels say they are fighting for land rights for tribal people and the rural poor. Their insurgency began in the eastern state of West Bengal in late 1960s, spreading to more than one-third of India's 600-plus administrative districts.
Though major offensives by security forces in recent years have pushed the rebels back to their forest strongholds and the levels of violence have fallen, but hit-and-run attacks are still common.
Former Indian Prime Minister Manmohan Singh had described Naxalite insurgency as the country's biggest internal security threat.
