At least 44 people have died and more than one million others have been stranded after days of torrential monsoon rains triggered devastating floods and landslides across southeastern Bangladesh.
The flooding has affected seven districts, leaving nearly 268,000 households cut off as damaged roads, power outages and broken communications hamper relief efforts.
Authorities, supported by the military, are using boats to deliver food, clean drinking water, medicines and other essential supplies to communities isolated by the rising floodwaters as the humanitarian crisis deepens.
According to Bangladesh's Ministry of Disaster Management, the worst-hit districts are Chattogram, Cox's Bazar, Bandarban, Rangamati, Khagrachhari, Moulvibazar and Habiganj.
The ministry said the flooding has disrupted daily life across the affected regions, isolating thousands of families and leaving 267,918 households stranded.
Days of relentless rainfall have inundated homes, submerged roads and destroyed key infrastructure, making it difficult for emergency responders to reach some of the hardest-hit areas.
Power outages and damaged communication networks have further complicated rescue and relief efforts, with many residents left without electricity or access to basic services.
For many families, the flooding has made even the simplest daily activities impossible.
"There is still water inside our home and we have no way to cook. The dry food we had has run out, and we spend the nights in the dark with our children because there is no electricity," said Nurul Islam, a resident of a flood-hit area in Chattogram.
Thousands of displaced families are now surviving on emergency food supplies such as flattened rice, puffed rice and biscuits that require no cooking, as kitchens remain submerged or covered in thick layers of mud left behind by the floodwaters.
Relief agencies have warned that washed-out roads and collapsed bridges continue to slow the delivery of humanitarian assistance, raising concerns that vulnerable communities could face worsening shortages of food, clean water and medical supplies.
Military personnel have joined the emergency response, transporting relief supplies by boat to areas cut off from the rest of the country.
Bangladesh is frequently hit by monsoon flooding during the rainy season, but the latest disaster has once again exposed the country's vulnerability to extreme weather events.
Authorities continue to monitor the situation closely as rescue operations and relief distribution intensify, while residents hope floodwaters will recede to allow them to return home and begin rebuilding their lives.
