First Pakistan team of climbers scale K2 summit
ISLAMABAD, A team of Pakistani climbers has reached the top of the world's second tallest mountain, the K2, the first since Italians scaled it 60 years ago.
The climbers reached the summit at 02:30 (22:30 GMT on Friday).
Correspondents, however, say descending from the top is more dangerous.
K2 lies near Pakistan's northern border with China. It is regarded by mountaineers as more challenging to conquer than Mount Everest, the world's highest peak.
Six Pakistanis – Hassan Jan, Ali Durani, Rahmat Ullah Baig, Ghulam Mehdi, Ali and Muhammad Sadiq – form part of the country's fist successful team to reach K2's summit. Three Italians are also part of the group.
Individual Pakistan climbers have reached the top before – but this is Pakistan's first successful team attempt.
The BBC's Shahzeb Jillani in Islamabad says many have died returning to the base camp in the past as the descent is trickier.
In June, the Italian organisation supporting the Pakistani effort announced it had installed a weather station feeding data to the climbers and researchers monitoring activity in high mountain regions.
Three Italians Achille Compagnoni, Lino Lacedelli and Ardito Desio, reached the top on 31 July 1954.
