Politician, family members among 11 killed in India ambush

"We are yet to ascertain the group responsible for the attack," the police official, who declined to be named as he is not authorized to talk to the media, reports Olaylar citing to Reuters

The area where the ambush took place is very remote, making investigation of the attack difficult, the official said.

Attacks on Indian officials by separatist militias have declined in recent years, though dozens of groups still operate in north and eastern areas of the country.

In April, five people including a lawmaker from India's ruling party were killed in the eastern state of Chhattisgarh when Maoist militants detonated a bomb as an entourage traveled back from a campaign appearance.
