By Bappa Majumdar KOLKATA, India, July 7 (Reuters) - Hundreds of thousands of people were marooned in India on Saturday as monsoon rains continued to ravage parts of the country, sparking fresh flooding. In Kolkata, the biggest city in eastern India, water was receding from some streets but in other areas of the city stagnant water was posing a serious health risk. "We are still concerned about waterlogging in some streets as it could trigger water-borne diseases," Sanchita Bakshi, a top health official said in Kolkata, capital of the communist-ruled state of West Bengal. "But the situation in the districts is bad now," she said. At least six districts in West Bengal remained cut off from the rest of the country after surging rivers broke through mud embankments and swamped hundreds of villages. At least 700,000 people were affected by the floods in the state and thousands were being evacuated to higher ground, officials said. In the neighbouring state of Orissa, some 1,000 villagers were rescued by soldiers in boats as water from the Subarnarekha river swamped 400 villages, affecting nearly 200,000 people. In the western state of Rajasthan, water breached a portion of a century-old dam, but authorities said they had the situation under control. A national highway was closed as a precautionary measure. "The villages are safe, but people were being moved to higher ground," Kiran Soni Gupta, a senior government official, said. International anti-poverty group ActionAid said in New Delhi on Friday at least 41 reservoirs across the country were choking with excess water and could result in more disastrous floods, especially in the west and south of the country. The western state of Gujarat was bracing for very different problem after being hit by floods in the past week. Officials warned farmers about a possible invasion by desert locusts from Africa. Flooding and storms have killed nearly 700 people across India, Pakistan, Bangladesh and Afghanistan over the past 15 days. (Additional reporting by Reuters reporters in Bhubaneswar and Jaipur)
