Attackers stormed a base camp at the foot of Pakistan's second-highest peak Nanga Parbat late Saturday, shooting dead 10 foreign trekkers, including three Ukrainians and a Pakistani guide at point-blank range.
Ukrainian Foreign Ministry spokesman Yevgen Perebiynis at a news conference condemned the "terrorist attack" and said the government had sent a note to Pakistan's acting representative in Ukraine calling for compensation and punishment of the guilty.
"We categorically demand compensation from the Pakistan side," he said, calling the attack "murder carried out with particular cruelty."
The three Ukrainians, identified as Igor Svergun, Dmitry Konyaev and Badavi Kashayev, were travelling in a group of six from the climbing club in the eastern city of Kharkiv, the president of the region's mountaineering and rock-climbing federation, Gennady Kopeika, told AFP.
It was the worst attack on foreigners for a decade in Pakistan and an unprecedented attack on tourists visiting the north, which until Saturday's shootings was considered immune from militancy plaguing other areas.
