Gunmen wearing police uniforms killed nine foreign tourists and one Pakistani before dawn Sunday as they were visiting one of the world's highest mountains in a remote area of northern Pakistan, officials said. The foreigners who were killed included five Ukrainians, three Chinese and one Russian, said Pakistani Interior Minister Chaudhry Nisar Ali Khan. One Chinese tourist was rescued, he said, according to AP. The attack took place at the base camp of Nanga Parbat, the ninth highest mountain in the world. It's unclear if they were planning to climb the mountain or were just visiting the base camp, which is located in the Gilgit-Baltistan region of Pakistan. The shooting is likely to damage the country's struggling tourism industry. Pakistan's mountainous north - considered until now relatively safe - is one of the main attractions in a country beset with insurgency and other political instability.
