A HERO climber has died after trying to help his friend trapped on a 25,000ft peak with a broken leg.
Luca Sinigaglia, 49, twice climbed back to the summit to bring essential supplies to his friend Natalia Nagovitsyna as emergency services race against time to rescue her.

The Italian climber died from low oxygen and hypothermia in the Tian Shan mountain range on the border with China.
He was taking essential supplies to his friend Natalia who had fallen and broken her leg while scaling the mountain on August 12.
Luca, a cybersecurity expert from Milan, died on August 15, on his second attempt to reach Natalia – just a few hundred metres from where she was taking cover.
His death comes as efforts to rescue Natalia have been obstructed by ongoing bad weather.
Four rescuers were injured during a search operation when a military helicopter was forced to crash-land.
