Passenger, driver quarrel to blame for deadly bus tragedy: police

A heated quarrel between a bus driver and a passenger was to blame for the tragic crash which killed more than a dozen in southwest China's Chongqing Municipality on Oct. 28, local police said at a news briefing on Friday. Authorities confirmed that at least 13 people have been killed after the bus veered onto the wrong side of the road and collided with an oncoming car before smashing through roadside barriers and flying off a bridge in Chongqing's Wanzhou District last Sunday.
