 ISLAMABAD, June 28 (Xinhua) -- Two foreign climbers attempting to scale world's ninth highest peak Nanga Parbat in northern Pakistan have gone missing, officials said on Wednesday. 
  
 Karrar Haidri, a spokesman of Pakistan's Alpine Club, said the climbers Alberto Zerain Berasategi, 55, from Spain and Mariano Galacan, 37, from Argentina went missing since Saturday while attempting to climb the 8,126-meter summit, known as the Killer Mountain in Gilgit-Baltistan region in north of Pakistan. 
  
 "A 14-member team of foreigners along with 50 local guides and porters started their campaign on June 18, but they had to quit their mission due to bad weather. Twelve members of the team have returned to the base camp while two of them are still missing," said Haidri. 
  
 The organizer of the campaign has sent a couple of rescue teams but they had to come back due to snow avalanche and inclement weather. 
  
 An army helicopter is now being used to search the missing mountaineers likely to be hit by the snow avalanche. 
  
 According to the Summit Karakoram, the organizer of the campaign, the two climbers stopped at an altitude of 6,100 meters for couple of days due to poor weather and when they restarted their campaign they lost the contact. 
  
 "Zerain and Galvan were last contacted through satellite device at 10:21 p.m. local time on Saturday when they were a little above 6,400 meters. This altitude is not considered dangerous, but the two mountaineers chose the hardest route which has been successfully completed only once in history," said the organizer. 
  
 Gilgit-Baltistan region, located in northern Pakistan and between the western end of the Himalayas, the Hindu Kush Mountains and the Karakoram Range, is home to five of the world's 14 peaks over 8,000 meters, including the world's second-highest mountain K2. Conditions are always harsh and tough and deaths not uncommon during campaigns at the mountains in the region. ||||| Two alpinists, a Spaniard and an Argentinian, have gone missing while attempting to summit Nanga Parbat, a peak in northern Pakistan nicknamed "Killer Mountain", mountaineering experts said on Tuesday. 
  
 "Alberto Zerain, a Spanish alpinist, and Mariano Galvan, an Argentinian national, went missing while trying to climb Nanga Parbat," Alpine Club of Pakistan spokesman Karrar Haidri told AFP. The moutain is the world's ninth highest. 
  
 Climbers stuck at 6,100 metres due to bad weather 
  
 Muhammad Iqbal, owner of Summit Karakorum, the tour operating company that had arranged the climb, said the duo had left base camp on June 19 but were holed up in their tent for three days at an altitude of 6,100 metres (20,000 feet) due to bad weather. 
  
 "They pushed for the summit again as the weather got better but lost contact with our staff at base camp on Friday," he told AFP. 
  
 "Our sherpas on the mountain estimate them to be somewhere above 7,000 metres which makes it impossible for them to climb and search so we have requested a search and rescue helicopter, which will start either today or tomorrow depending on weather conditions," he added. 
  
 First successful climb of Nanga Parbat in 1953 
  
 At 8,125 metres, Nanga Parbat earned its grisly nickname after more than 30 climbers died trying to conquer it before the first successful summit in 1953. The first successful winter climb of the mountain was carried out in February 2016 by a team including Alex Txikon.

 In 2013 gunmen shot dead 10 foreign climbers and their Pakistani guide at the Nanga Parbat base camp - one American with dual Chinese citizenship, two other Chinese, three Ukrainians, two Slovakians, one Lithuanian and one Nepalese. 
  
 Northern Pakistan is a magnet for mountaineers and is home to some of the tallest mountains in the world, including K2 - at 8,611 metres, the world's second highest peak, but deemed a more challenging climb than the highest, Mount Everest. 
  
 Nestled between the western end of the Himalayas, the Hindu Kush mountains and the Karakoram range, the Gilgit-Baltistan region houses 18 of the world's 50 highest peaks. 
  
 It is also home to three of the world's seven longest glaciers outside the polar regions. Hundreds of its mountains have never been climbed. |||||
It's dubbed "Killer Mountain," a name that will be hardly comforting to family members of two climbers lost on the peak in Pakistan since the weekend. Alberto Zerain Berasatei of Spain and Mariano Galacan of Argentina were part of a team that began climbing the world's ninth-highest mountain, Nanga Parbat, this month. But while all other team members have returned to base camp, Berasatei, 55, and Galacan, 37, are missing, reports Reuters. The owner of tour company Summit Karakoram, which arranged the climb, tells AFP the pair reached a height of 20,000 feet last week but were then forced to spend three days in a tent due to bad weather. "They pushed for the summit again as the weather got better but lost contact with our staff," he says. The owner adds sherpas believe the climbers are above 23,000 feet on the 26,660-foot-tall mountain, a height he says is "impossible" for rescuers—though Reuters reports rescuers were scouring the mountain Wednesday as poor weather kept helicopters grounded. A rep for Summit Karakoram tells Xinhua that the "altitude is not considered dangerous, but the two mountaineers chose the hardest route which has been successfully completed only once in history." Hopes of finding the men alive don't appear to be high. "In such weather conditions and without adequate food supply, survival appears unlikely," says a rep for the Alpine Club of Pakistan. Xinhua reports the climbers may have fallen victim to an avalanche that forced rescuers to turn back. (Three corpses were taken off Everest, and not without controversy.)
