Indian police shot dead 10 Maoist guerrillas in southern Andhra Pradesh state on Monday while rebels destroyed a railway station in a separate overnight attack, officials said. The new violence comes after peace talks between the state government and the rebels collapsed in January. The Maoists were killed in the forests of Nizamabad district, 190 km south of the state capital, Hyderabad, one of India's gleaming IT hubs. "The violence by Naxals (Maoists) has increased after peace talks have broken down," Superintendent of Police Madhusudhan Reddy told Reuters by phone, adding police had suffered no casualties in the firefight which lasted for over an hour. Separately, Maoists killed a policeman in the east of the state. More than 6,000 people have died in the 30-year-old Maoist insurgency in Andhra Pradesh, a largely farming state where hundreds of farmers have committed suicide since 2003 under the burden of debt.
