A group of trekkers from West Bengal, were stuck near Rupin Pass on the way to Sangla valley in Himachal Pradesh's Kinnaur district, an official said on Thursday.

Soon after the trekkers were reportedly stranded, an Indian Air Force helicopter was sent to rescue them, but it could not land at the site due to adverse weather on Thursday evening, the official said.

The rescue operation would resume Friday at 5 am, he added.

Trekker Sudha Bhattachargee was also reported to have injured her leg, the official said.

The trekkers were on their way to Sangla valley in Kinnaur district via Rupin Pass from Dhaula in Uttarkashi district of neighbouring Uttarakhand, he added.

Shimla Deputy Commissioner Amit Kashyap earlier got the information about the stranded trekkers and he brought it to the notice of Chief Minister Jai Ram Thakur.

The chief minister directed Additional Chief Secretary (Revenue) Shrikant Baldi to ensure their rescue, he added.

Shrikant Baldi requested the IAF to rescue the stranded trekkers, following which a helicopter was pressed into service, he said.
