Three bus crashes in China have left at least 23 people dead and 48 others injured or missing, state media reported. The official Xinhua News Agency said 12 people were killed and five were missing after their bus plunged into a river in Tibet. The driver and one passenger were the only survivors. The accident happened Tuesday but was not reported until Saturday. Nine people were killed and seven seriously injured in the far west region of Xinjiang on Saturday when a long-distance bus collided with a heavy-duty truck, Xinhua said. In the third accident, Xinhua said two tourists from Hong Kong were killed and 36 others were hurt when their bus overturned after colliding with a farm vehicle Friday night in Jilin province in northeastern China.
