Heavy rain early on Sunday triggered multiple landslips in Sikkim, snapping road connectivity between Gangtok and West Bengal.
According to a senior official, huge boulders have jammed National Highway 10 at two places—19 Mile and 20 Mile—between Singtam and Rangpo in East Sikkim.
The road leading to Gangtok from Singtam also lay blocked at 32 Mile, he said.
