The 10 foreigners dead included two Chinese, one Chinese-American, one Nepalese, and one Pakistani guide, said the home secretary in the Gilgit-Baltistan area where the attack took place. The local Taliban took responsibility for the killings, saying it was to avenge the death of a leader killed in a US drone strike on May 29. "By killing foreigners, we wanted to give a message to the world to play their role in bringing an end to the drone attacks," said a spokesman. The attack took place at the base camp of Nanga Parbat, the ninth highest mountain in the world at 26,660 feet. The BBC reports the group intended to climb the mountain, which is known as the "killer mountain" because of numerous mountaineering deaths there in the past. "The government of Pakistan expresses its deep sense of shock and grief on this brutal act of terrorism," said a statement by the foreign ministry, saying it would "take all measures to ensure the safety of foreign tourists."
