Sikkim flash flood: Search and rescue operation continues, situation normal along LAC

A Glacial Lake Outburst in South Lhonak Lake in North Sikkim on the night of 03-04 Oct caused a devastating flood in the North Eastern State of Sikkim. 

The level of water in the Teesta River increased by about 50-60 feet in height which caused calamitous floods downstream. Large-scale damage to infrastructure, and property and loss of human lives have been reported. 

The exact assessment of the damage is yet to be corroborated due to the inclement weather and incessant rains.

Indian Army deployed in the area has also been affected with some of its camps along the Teesta River bank being damaged/ washed away. A vehicle parking area at Burdang near Singtam was affected by the flash flood and 23 soldiers and 39 vehicles that were taking a temporary overnight transit halt have been submerged in silt or swept away.
