Hyderabad: Six persons of a family, including three children, died when a mob set fire to a house in Watli village during fresh communal violence in Adilabad district of Andhra Pradesh.

Police failed to prevent the attack on early Sunday morning though they had been warned that there could be communal violence in the village. No senior officers were in the village at the time of the attack.

District Collector Ahmed Nadeem told PTI three of the dead couldn't be recognised and all the bodies had been sent for autopsy.

Nadeem, who has ordered a magisterial inquiry into the incident, said five of the dead were from Hyderabad and were visiting their parents' home in the village for Dussehra festival.

Andhra Pradesh Home Minister K Jana Reddy held a meeting with senior officials in Hyderabad and would visit Bhainsa.

Taking a serious note of the incident, Chief Minister Y.S. Rajasekhara Reddy asked district police to be on high alert and prevent the spread of violence.
