Five Ukrainian nationals were among nine foreign tourists killed in an unprecedented attack in Pakistan's normally peaceful Himalayan region, Ukraine's ambassador to Islamabad said on Sunday.
"Minimum 10 people were killed, of them five were Ukranian nationals," ambassador Vladimir Lakomov told AFP.
A spokesman for the Ukrainian foreign ministry in Kiev described the overnight attack as a "terror act."
Police in Pakistan said gunmen had killed nine tourists and a Pakistani at a base camp for Nanga Parbat, one of the world's highest mountains.
"Around 1 am militants surrounded a tent camping site around the mountain Nanga Parbat and shot dead people who were in it," Lakomov said, adding that the victims were believed to be mountain climbers.
The embassy was in contact with local police to identify the Ukrainians, he Lakomov added.
The victims are believed to include Chinese and Russians.
A representative of the Russian embassy in Islamabad refused to confirm or deny reports that a Russian was among the dead.
"We do not have any personal data yet," the official told AFP on condition of anonymity. "So far we do not have confirmation from the local authorities."
He said if there were some tourist groups from Russia staying in Pakistan, they had not been registered with Russia's Federal Tourism Agency. "They often come on their own," he said. "That's the usual practice here."
