　　(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. And the rain this time was relentless, lashing the city in much of the northern coast of Cuba for more than 24 hours. The downpour turned city streets into rivers. The seafront Malecon was closed as waves crashed over the wall. (4)Families bailed water from their homes and outside traffic police at some junctions stood up to their waists in the water. "
