Two bombs planted by suspected Maoist rebels have killed at least 12 people in the eastern Indian state of Chhattisgarh as voting continues in the general election.
The first blast hit a bus carrying election officials in Bijapur district, police said, killing seven.
The second attack nearly half an hour later killed five police in an ambulance in the Bastar district.
Officials said the bus in Bijapur district was blown up by a landmine as it traveled between Gudma and the town of Kutru. Four people were injured.
India began five weeks of general election polling last Monday
