Residents of Ruiarbil village in Satkhira's Ashashuni upazila are living in fear of flooding as a large portion of the embankment along the Kopotakkho river has developed a crack. Not only Ruiarbil, local people say that as many 19 nearby villages in the upazila could be inundated during this monsoon if the Water Development Board does not take steps to protect the embankment from erosion at the earliest.
