maoist attacks continued, primarily on government and police targets. civilians were also affected in landmine attacks affecting railway cars and truck convoys. clashes between state police and rebels also resulted in deaths of members of both parties, and civilians that were caught in the firing. fighting differs from state to state, depending on security and police force responses. in the state of andhra pradesh, security forces have been somewhat successful in maintaining control and combating maoist rebels. the other state that is most affected, chhattisgarh, has seen an increase in violence between maoist rebels and villagers who are supported by the government. in 2006, 500 to 750 people were estimated killed, fewer than half naxalites, and approximately one-third civilians.
