Ranchi, May 23 (ANI): Police arrested four hardcore Maoists in India's red corridor of Gulma district and interiors of Ranchi in Jharkhand and recovered arms, ammunition and a number of mobile phones. Two of the arrested Maoists were area commanders of the red rebel outfit. The police launched combing in the area and were successful in nabbing the Maoist on Thursday. Maoists, also known as Naxals, have killed police and politicians, and targeted government buildings and railway tracks in an insurgency that has killed thousands since the 1960s. The Maoists, who say they are fighting for the rights of the poor and landless, control some of India's mineral-rich areas and operate in large areas of the eastern, central and southern countryside.
