Gangtok, Sept 14 : Incessant rain for the past few days has triggered multiple landslides in Sikkim and Darjeeling, snapping road connectivity at several places, officials said Friday.
The landslides have occurred at Dzongu, Mangan, Lachen and Mangshilla in North District and at two places near Sevoke, around 22 kms from Siliguri city, they said.
The two landslides -- at the 29th Mile and 10th Mile areas -- occurred at around 3 am Friday, the officials said.
The Border Roads Organisation (BRO) has arranged for small cars to pass through the two areas but large vehicles have been barred.
Mangan, which houses the headquarters of North Sikkim district, has been cut off from Gangtok due to a landslide at Ambithang.
The road link between Mangan and Chungthang has also been snapped after a bridge was washed off at Rafong Khola.
The Ambithang Jhora is also flowing in full spate, damaging culverts and a newly constructed bailey bridge near Toong has been damaged.
