Thane, July 31 (IANS) Three people from Rajasthan, including a 12-year-old boy, were killed when a passenger bus rammed into a stationery truck on the outskirts of Maharashtra's Thane district early Saturday, officials said.

The luxury bus was on a trip from Rajasthan to Mumbai when the accident took place on the Mumbai-Ahmedabad Highway around 5.30 a.m., said Ravindra Kharde, an official at the Kasa police station.

The victims were identified as Jalaram B. Dudhi, the 45-year-old bus driver, Bhagirath P. Ramjisyag, the bus attendant, and Nandlal D. Chauhan, a 12-year-old passenger, Kharde said.
