DHAKA (Reuters) - Catastrophic floods in Bangladesh have spread to the north of the country and people marooned in remote villages are faced with starvation, officials said on Thursday. The monsoon-fed floods have killed at least 84 people across the country, officials from the Flood Forecasting and Warning Centre said. They said fresh areas, mainly in the northern part of the country, had been flooded after 24 hours of continuous rain, which ended at 0000 GMT on Thursday. Flood monitors with the water development board said that all Bangladesh‘s rivers were above their danger levels and were expected to continue rising. The popular Bengali daily Janakantha put the death toll higher. This is the second round of flooding this month. An earlier deluge killed at least 29 people, mostly in the southeast, according to official figures. Most of the deaths have been from drowning and landslides but there is now a threat of starvation for people marooned in remote villages unless aid can reach them. Over seven million people have been affected, including more than 600,000 marooned in their half-submerged homes. Others put the number of flood victims at nearly 10 million. The country has a population of 124 million. The government has already alerted security forces including paramilitary guards. Hundreds of Bangladeshis die in floods every year. Officials said they did not anticipate major agricultural losses because most crops had been harvested before the flooding started.
