Police say at least 17 people have been killed and 35 injured when a packed bus collided with a truck in the northern Indian state of Uttar Pradesh. State police spokesman Surendra Srivastava says seven of those injured in Sunday's accident are in critical condition. He says it is not immediately clear what caused the truck to veer into the path of the bus near Etah, a town about 185 miles (300 kilometers) southwest of Lucknow, the state capital, according to a report of the Associated Press.
