Hyderabad, Aug 29 (IANS): Three persons were killed in a road accident in Mahabubnagar district of Telangana on Thursday.

Four others were critically injured in the accident.

The accident occurred near Momidi in Chillakur mandal of Tirupati district when the bus belonging to Andhra Pradesh State Road Transport Corporation (APSRTC) entered into an agricultural field.

The APSRTC bus was heading to Kota from Nellore via Muttukuru. There were 35 passengers onboard the bus.

Three passengers sustained grievous injuries while some other passengers sustained simple injuries.

According to eye-witnesses, the bus driver showed presence of mind to avoid hitting the autorickshaw but in the process, the bus steered off the road and entered into the agriculture field abutting the road.

Alerted by the locals, police rushed to the spot and shifted the injured to a nearby hospital.
