Police say gunmen killed 11 people, 10 of them foreigners, after barging into a hotel where the victims were staying in northern Pakistan.

The group of tourists from Russia, the Ukraine, and China were staying in Pakistan’s Gilgit-Baltistan region in order to climb  Nanga Parbat, one of the world’s highest mountains.

The gunmen have yet to be identified and their motives are currently unknown.

Local police chief Barkat Ali says the climbers from Russia, China and the Ukraine were killed before dawn Sunday as they set off to climb Nanga Parbat, a popular destination for trekkers, in the Gilgit-Baltistan area of Pakistan.

The gunmen are said to have stormed into the hotel where the tourists were staying, according to Sky News.

No one has yet claimed responsibility for the attack.

A senior government official told reporters that a large number of security personnel have been sent to Gilgit-Baltistan in the wake of the shooting spree.

‘Since the area is very remote with no roads or transport, their bodies will have to be retrieved by helicopter,’ the official said, according to Sky News.
