CALCUTTA, India, November 09, SPA -- Maoist rebels fired at a police patrol guarding a shopping area in eastern India over the weekend, killing four officers, authorities said Monday. The attackers escaped into a nearby forest as two other police officers chased them and exchanged gunfire in Gidhni, a small town nearly 110 miles (180 kilometers) southwest of Calcutta, the capital of West Bengal state, said Noman Hossain, a police officer. The rebels took away the rifles of the slain police officers, Hossain told The Associated Press. The Communist Party of India (Maoist), a key rebel group in the region, claimed responsibility for the killings, the Press Trust of India news agency said. --SPA 13:16 LOCAL TIME 10:16 GMT www.spa.gov.sa/717193
