ISLAMABAD — Police say gunmen have killed 11 foreigners who were climbing one of the highest mountains in the world in northern Pakistan.

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 in the Gilgit-Baltistan area of Pakistan.

No one has claimed responsibility for the attack.

Nanga Parbat is the ninth-highest mountain in the world and is notoriously difficult to climb.
