The death toll in a land mine blast in central India has risen to 24, after another soldier succumbed to his injuries. Authorities blame Maoist rebels for the attack on an armored vehicle carrying paramilitary soldiers late Saturday in Bijapur district in the state of Chhattisgarh. They say three other soldiers who survived the explosion are battling for their lives. Thousands of people have been killed in Maoist rebel violence in India over the past three decades. Maoist guerillas are active in eight of India's 29 states and say they are fighting for the rights of poor, landless agricultural workers. New Delhi says they also have links with Maoist rebels fighting to topple the monarchy in Nepal.
