Seven villages in Fulgazi upazila of Feni district have got submerged as the flood control embankment along the Muhuri River collapsed due to the onrush of water, destroying crops and dwellings.
The river was flowing 140 cm above its danger level, cutting off road communications with Parshuram areas.
Sources at the upazila administration and Water Development Board (WDB) said the embankment at Jaipur point in Fulgazi Sadar Union got damaged due to the deluge of water from across the border.
They said the floods sent Fulgazi Sadar Union, West Ghaniamora, East Ghaniamora and Kismat Ghaniamoa, Jaipur, North Daulatpur, South Dinajpur and Bairagpur areas under water, damaging houses and huge crops.
Fulgazi Union Parishad (UP) chairman Nurul Islam said the floodwater poured into the villages through the damaged parts of the embankment at Jaipur part in Sadar Union.
