A collision between a passenger bus and a truck killed more than 30 people Saturday in the West African nation of Burkina Faso, the state radio reported. The crash occurred before dawn on a thoroughfare west of the capital, Ouagadougou, the radio reported. Fire swept through the bus after the crash, and at least 34 people died and others were injured, it said. There was no immediate word on the cause of the crash, and officials were not immediately available for comment from the remote accident site. "It's horrible, the firefighters are still battling the flames in the bus, with bodies inside," Moussa Souna, a local journalist, told The Associated Press by telephone from the scene nearly eight hours after the crash. Road accidents are common across West Africa, particularly toward the end of the rainy season when already degraded roads are washed out and potholes fill with water.
