Monday, authorities in India and Bangladesh scrambled to distribute food and water to hundreds of thousands of evacuees displaced by days of flooding that swamped large portions of both nations.
The monsoon rains-caused floods have killed more than a dozen people, stranded millions, and inundated millions of homes.
In the northeastern Bangladeshi city of Sylhet along the Surma River, residents swam through knee-deep flooded streets. One man stood at the entrance of his flooded store, where the upper shelves were stuffed with merchandise to keep it above water. Local television said that millions remained without power.
The junior minister for disaster and relief, Enamur Rahman, stated that up to 100,000 people had been evacuated from the worst-affected districts, including Sylhet. According to the United News of Bangladesh, around 4 million people are stranded.
In India's northeastern Assam state, two police officers assisting in rescue attempts were swept away by floodwaters on Sunday, according to state officials. They reported that over 200,000 people were taking refuge in 700 relief centers. All of the state's significant rivers had dangerously high water levels.
Monday, Chief Minister Himanta Biswa Sarma announced that his administration is utilizing military helicopters to ferry food and fuel to areas of the state that have been severely damaged.
After weeks of excessive rainfall, the Brahmaputra River overflowed its banks in Assam, submerging millions of houses and destroying transportation lines. Assam has previously been devastated by major flooding.
The Brahmaputra flows from Tibet through India and into Bangladesh, passing through Assam on its almost 500-mile (800-kilometer) trip.
Major roadways were swamped in the affected regions of Bangladesh, leaving people stuck. In a country with a history of calamities caused by climate change, many citizens have expressed frustration that local officials have not done more.
"Not much can be said about the issue. The water is seen with one's own eyes. The water level within the chamber has decreased slightly. It used to reach my waist," said Sylhet grocery store owner Muhit Ahmed.
On Friday, Bangladesh dispatched soldiers to assist with evacuating refugees, but Ahmed has not yet seen any.
"We are in a dire situation. He stated that neither the Sylhet City Corporation nor anyone else had come to ask about us. "I am attempting to save as much of my possessions as possible. We are now at our maximum capacity.
Sunday, the National Flood Forecasting and Warning Center reported that flooding in the northeastern districts of Sunamganj and Sylhet could intensify. It was stated that the Teesta, a significant river in northern Bangladesh, may exceed danger levels. According to the report, the situation could deteriorate in other northern districts.
Officials reported that floodwaters had begun receding in the northeast but continue to threaten the central region, from which water flows south into the Bay of Bengal.
According to media accounts, communities in rural regions struggle to acquire potable water and food.
BRAC, a private nonprofit organization, built a center to prepare food for 5,000 households in one affected district on Monday, but the arrangements were inadequate, according to senior director Arinjoy Dhar. In an internet video, Dhar requested assistance in delivering food to flood-affected individuals.
A pre-monsoon flash flood driven by water from upstream in India's northeastern states struck northern and northeastern portions of Bangladesh last month, devastating crops and causing damage to homes and highways.
Bangladesh is predominantly flat and low-lying, so short-term floods during the monsoon season are frequent and frequently helpful for agriculture. However, disastrous floods wreak havoc on the nation's infrastructure and economy every few years. According to the World Bank, over 28 percent of the nation's 160 million people reside in coastal regions.
In 1988, during one of the most significant floods, most of the country was submerged. In 1998, another catastrophic flood swamped over 75% of the nation. In 2004, there were longer-lasting floods.
According to scientists, climate change has aggravated the flooding in Bangladesh. According to the Intergovernmental Panel on Climate Change of the United Nations, approximately 17 percent of the population may need to be relocated within the next decade or two if global warming continues at its current rate.
