FLOOD ALERT IN WEST BENGAL; HEAVY RAINS IN SIKKIM

"The water of Teesta is rising because of the release of water from barrages in Sikkim. Teesta is coming down with great speed and an alert has been issued in this regard. We have taken all precautionary measures. Leaves of all the officials have been cancelled," the official told PTI.
The Jalpaiguri administration also used public address system asking residents near Teesta to move to a safer location, advising fishermen to not venture into the river.
"Everything from boats to rescue equipment has been kept ready. Residents have been asked to leave river banks," said an official of the Jalpaiguri Sadar Sub-Divisional office.
Meanwhile, incessant downpour triggered landslides in Sikkim, causing severe damage to the roads, vehicles and houses.
Sikkim Chief Minister Prem Singh Tamang directed authorities, police and other officials to ensure quick response to any requirements in the rescue and relief operations.
