Schools have been converted into makeshift shelters and troops have been deployed to evacuate households cut off from neighbouring communities as a result of rising waters.
“The whole village went under water by early Friday and we all got stranded,” Lokman, whose family lives in Companiganj village in Bangladesh, told AFP news agency.
“After waiting a whole day on the roof of our home, a neighbour rescued us with a makeshift boat. My mother said she has never seen such floods in her entire life,” the 23-year-old added.
In Assam state in neighbouring India, more than 1.8 million people have been affected by floods after five days of incessant downpours.
Assam Chief Minister Himanta Biswa Sarma told reporters he had instructed district officials to provide “all necessary help and relief” to those caught in the flooding.
“Our house is submerged in water. I’ve never seen such huge floods in my life,” Husna Begum, a resident of Udiana village in Assam, told the BBC.
The 28-year-old has been living in a rickety plastic tent with her children since Thursday. “There is no drinking water in the camp here. My son has a fever but I am unable to take him to the doctor,” she said.
Ronju Chaudhary, who lives in the same village, described the scale of the flooding. “We are surrounded by water on all sides. There’s water inside our homes too,” he said.
This week’s rains come as Bangladesh’s Sylhet region was still recovering from its worst floods in nearly two decades in late May, when at least 10 people were killed and four million others were affected.
Syed Rafiqul Haque, a former lawmaker, said Bangladesh was at risk of a humanitarian crisis with “almost the entire Sylhet-Sunamganj belt.. under water and millions of people… stranded”.
Some 3.1 million people were displaced in the region, officials said, with 200,000 of them now being housed in makeshift shelters on higher ground.
Seasonal monsoon rains represent a lifeline for farmers across South Asia, but typically cause deaths and destruction to property every year. Bangladesh and India have both experienced increasingly extreme weather in recent years.
Environmentalists – while not ascribing single weather events to climate change – do warn it could lead to more disasters, especially in countries that are low-lying and densely populated, as reported by BBC.
