Floods unseen in northeast Bangladesh for almost two decades began to recede on Sunday after about 60 people died in the country and neighboring India in a week, according to authorities. Rescuers who went to the affected area are trying to help millions of isolated people. These floods have claimed the lives of at least ten people in Bangladesh and fifty people in India.

In Bangladesh, flood waters from northeast India caused a large dam on the Burak River, shared by the two countries, to crack, flooding at least a hundred villages. About 70 percent of the region’s largest city, Sylhet, and about 60 percent of Sonamjang district were hit by floods, Arifuzman Boyan, head of the Bangladesh government’s Flood Monitoring and Prevention Center, told AFP.

“This is one of the worst floods in the region,” he said, adding that the situation will improve further in the coming days after the heavy rains stop. Sylhet District Chief Mozipur Rahman said the Zakigang dam on the border with India could only be repaired when the water level dropped.

Nearly 50 people died in India last week due to floods, landslides and thunderstorms, according to local disaster management officials. In the state of Assam (Northeast India), 18 people have died, according to authorities, and more than 92,000 people have been displaced. In Bihar, west of Assam, a thunderstorm killed at least 33 people on Thursday. The state experienced a heat wave during the week, with temperatures reaching 40 degrees Celsius.
