Ukraine and Pakistan are holding negotiations on the payment of compensation to the families of Ukrainian climbers killed in a terrorist attack in Islamabad, the Ukrainian Foreign Ministry has reported.

"This issue is on the agenda of a meeting with the Pakistani side. We feel that Pakistan is sympathetic to this situation, and the negotiations are ongoing," deputy director of the ministry's information policy department, Vasyl Zvarych, said at a briefing in Kyiv on Tuesday.

He also said that two Ukrainian climbers who remained in Islamabad after the terrorist attack to coordinate work on the return of equipment owned by the members of the expedition returned to Ukraine on July 3.

Earlier reports said that three Ukrainians, two Chinese nationals, one Lithuanian, two Slovak citizens and one Nepali national died in an extremist attack on a hotel in the north of Pakistan's Kashmir on the night between June 22 and 23. One of the victims also held a US-Chinese passport.

The international expedition, which included climbers from Ukraine, Georgia and Slovakia, lead by Ukrainian climber Ihor Sverhun, was to conquer Nanga Parbat (8,125 meters high).

The incident occurred in Gilgit-Baltistan, an area that had been considered one of the safest parts of Pakistan, although in recent years it had seen several attacks by radicals on members of the Muslim Shia minority.

An extremist militant group known as Jundallah claimed that they were behind the attack. Later, another militant group, Tehrik-i-Taliban Pakistan, also claimed responsibility for the attack.
