　　(3)Heavy rain has been battering Cuba since Friday, causing widespread flooding and killing at least two people. Many buildings are collapsed under the weight of the torrential downfalls in the capital Havana. From there Sarah Rainsford reports. "Every time there is heavy rain, residents of the older parts of Havana worried a lot because much of the housing there is poorly maintained and in a highly precarious state.
