Many embankments, roads and homesteads have been damaged in many districts of the country due to flood, causing immense sufferings to people.
Water of the Brahmaputra, the Jamuna, the Padma and the Meghna may further rise, according to a bulletin of Flood Forecasting and Warning Centre (FFWC).
Some 14 rivers across the country were flowing above danger marks, said the bulletin.
Around 30 villages in Sadar upazila have been flooded freshly as around 400 meters of Dharla's alternative dyke collapsed in Kurigram.
"Our entire union has been submerged after the dyke collapsed," said Omar Farooq, chairman of Holokhana Union Parishad in the upazila.
He also alleged that the dyke collapsed due to negligence of Water Development Board (WDB).
However, Ariful Islam, executive engineer of Kurigram WDB, said locals cut the dyke indiscriminately. It had made the dyke vulnerable and collapse.
