A vast area in Khalisha Chapani, Tepa Khoribari, East and West Chhatnai, Tawabari and Kolmunda unions of Dimla and Jaldhaka upazilas went under water.

At least 20 Teesta chars including Jhar Singeshwar, Baika Pukur, Chhtunama, Vendabari, Bhasanir Char, Fakrater Char, Satighat and Haldibari are reeling under five feet water.

About 6,000 homeless people of these chars took shelter on two embankments of the Teesta. Most of them are starving due to lack of food.

Around 800 people of more than 300 families of the town also took shelter at the district Ansar-VDP office as rainwater entered their houses.

Floodwaters entered every house of Progotipara, Saudagarpara, New Babupara, Dangapara and Baroipara areas of the town.

The entire district plunged into darkness when a 33,000-volt electric tower in Sadar upazila collapsed during heavy rain on Monday night.

The rivers Teesta, Charalkata, Burikhora, Buri Teesta, Kewnai, Panga, Jamunashwary swelled due to onrush of water from the upstream India.

Sources said the water flow in the rivers in the district increased as all the sluice gates of the Gazaldoba Barrage in India have been opened.

Movement of vehicles on the Nilphamari-Dhaka highway was disrupted as the soil of about 70 metres stretch of the road subsided near Kazirhat in Sadar upazila.

Deputy Commissioner Rabindranath Roy Chowdhury visited the flood-affected people at the Ansar-VDP office and arranged food for them.
