Heavy monsoon rainfall and flash floods battered southeastern and northeastern Bangladesh during early July 2026, killing at least 51 people and marooning over 1 million residents. The relentless, torrential rains triggered widespread flooding across at least 10 heavily affected districts, including Chattogram, Cox's Bazar, Bandarban, Rangamati, Khagrachhari, Moulvibazar, and Habiganj.
More than one million people have been affected, with thousands of homes, roads, bridges, and agricultural lands inundated, leaving more than 267,000 families entirely marooned by high waters. The disaster also triggered severe landslides, particularly in the hilly areas and Rohingya refugee camps of Cox's Bazar, resulting in heavy casualties and mass displacement. Over half of the recorded deaths, at least 28 fatalities occurred in Cox's Bazar, where more than one million Rohingya refugees live in highly dense, deforested, hillside settlements that are extremely vulnerable to mudslides.
In response to the crisis, roughly 50,000 displaced people have fled their homes to seek safety across more than 1,100 temporary government shelters. Border Guard Bangladesh and tri-services military units have been actively deployed across the hard-hit districts to manage high-risk rescue missions and clear major transit routes. Simultaneously, emergency medical teams from the Directorate General of Health Services are working to distribute clean drinking water, provide emergency medicines, and prevent waterborne disease outbreaks.
While relief operations are ongoing, continued heavy rainfall poses a persistent risk of further flooding and landslides. Although meteorologists from the Flood Forecasting and Warning Centre (FFWC) expect conditions to slowly improve in the southeast, heavy onrushing waters from transboundary rivers in upstream India mean that northern and northwestern districts in the Brahmaputra Basin remain at immediate risk of further inundation.
