Heavy monsoon downpours swelled rivers across the country worsening the ongoing flood situation in the north-eastern districts of Sylhet, Sunamganj, parts of Lalmonirhat, Netrakona, Sherpur and Kurigram. At least a million people have been left marooned. Nine units of the Bangladesh Army started rescue operations in flood-hit Sylhet and Sunamganj districts in the afternoon. “The troops are working in Sylhet sadar, Gowainghat, Kompaniganj, Sunamganj sadar, Dirai, Chhatak, Doarabazar and Jamalganj upazilas to rescue the waterlogged people from their homes by boat and take them to safe shelter,” said Major General Hamidul Haque, (general officer commanding) of Sylhet Cantonment. Major General Hamidul Haque said that the power supply in Sylhet Kumargaon power plant was under threat due to rising water level that may force it to shutdown. From noon, the army began construction of a dam with sandbags around the Kumargaon power substation. Besides, an attempt is being made to dry the water entering the power plant with the help of Sylhet City Corporation's sucker machine. Sylhet City Corporation Mayor Ariful Haque Chowdhury said, ”If the Kumargaon substation sinks, power connection to the whole district will be snapped cutting off all communication. So we are trying our best to keep this station running.” Besides, army members are trying to protect several food warehouses in Sunamganj. Meanwhile, flight operations at Sylhet MAG Osmani International Airport have been suspended for next three days as the flood waters encroached on the runway. A total of 367 educational institutes suspended classes as the buildings remained under the water in seven upazilas including the Sylhet sadar, said officials of the district Education Board. The government is indefinitely postponing the Secondary School Certificate (SSC) and equivalent examinations under all education boards scheduled to begin from June 19. The news came as a relief for the flood-hit regions. Shahjalal University of Science and Technology (SUST) has been closed till June 25 in a decision taken at an emergency syndicate meeting Friday morning. Sunamganj Flood situation in Sunamganj went out of hand on Friday as the communication system of the district completely broke down. Sunamganj municipality mayor Nader Bakht said, "Water has entered almost all the roads and houses in the municipal area. People are seeking refuge in the highlands. The residents of the town have fallen into a terrible disaster.”
