India police in 'shooting mishap'

Two police patrols in south-east India have fired on each other by mistake, leaving one policeman dead and two others injured, police say.

They said the patrols both believed they were coming under attack from Maoist rebels active in the area.

The incident took place in dense forest in the state of Andhra Pradesh, near the border with Chattisgarh.

The area is a stronghold of the Maoists, who have been waging an armed campaign for four decades.
