Floodwater rushing from India's northeast breached a major embankment on the Barak River, inundating at least 100 villages at Zakiganj in Bangladesh, said Mosharraf Hossain, the chief government administrator of the Sylhet region, AFP reported.
"Some two million people have been stranded by floods so far," he told AFP, adding that at least 10 people have been killed this week.
Many parts of Bangladesh are prone to flooding, and experts say that climate change is increasing the likelihood of extreme weather events around the world.
Every extra degree of global warming increases the amount of water in the atmosphere by about seven percent, with inevitable effects on rainfall.
In Zakiganj bus driver Shamim Ahmed, 50, told AFP: "My house is under waist-deep water. There is no drinking water, we are harvesting rainwater.
Floodwater has entered many parts of Sylhet city, the largest in the northeast, where another official said about 50,000 families had been without power for days.
Hossain said the flooding was driven by both rains and the onrush of water from across the border in the Indian state of Assam.
But officials said the broken embankment on the border at Zakiganj could only be fixed once the water level dropped.
