More than 50 Maoist insurgents attacked a police station in India's impoverished Bihar state, killing two policemen before blowing up the building with dynamite, police said on Friday, according to Reuters. Two policemen were seriously wounded in the attack late on Thursday at Chabilapur, about 125 km (80 miles) south of Patna, the capital of the eastern state. "The policemen resisted the Maoists and an exchange of fire took place. But the police force was overpowered," said Birhar's Inspector General of Police R.R. Verma, adding that a number of policemen escaped before the station was blown up. The Maoists took weapons abandoned by the officers. Maoist guerrillas, who operate in at least eight Indian states, say they are fighting for the rights of poor peasants and landless labourers in the country's rural hinterland and regularly ambush police patrols and set off explosions. New Delhi says Indian Maoists have links with Maoist rebels in Nepal fighting to topple the rugged nation's monarchy.
