Police in southern India killed four Maoist rebels _ including a top commander _ during a gunbattle in a dense forest, a senior officer said. Rebel commander D.V.K. Swamy, alias Yadanna, was killed along with three other guerrillas in a fierce gunfight that lasted several hours, said police officer Batti Lal Meena. Swamy supervised operations in Warangal district, the rebels' biggest stronghold, and nearby areas. The gunfight occurred in the dense Venkatapuram forest in Warangal, about 210 kilometers (130 miles) north of the Andhra Pradesh state capital, Hyderabad.
