At least 20 people have been killed in southern India in a blast that destroyed a bus.
The explosion took place late Monday as the bus traveled through a forested area north of the Andhra Pradesh state capital, Hyderabad.
The Associated Press quotes police as saying they suspect leftist guerillas were behind the blast.
Five members of the Maoist People's War Group were killed in a firefight with police last week in the same area.
The rebel group is fighting for an independent homeland in five southern Indian states. The rebels mostly target rich landowners, accusing them of exploiting landless farm workers. They also attack police and government officials.
