Pakistani mountaineer Murad Sadpara did the impossible by conquering the treacherous Nanga Parbat twice in a single week.

Sadpara completed his second climb on Monday and he did it without an oxygen tank.

Nanga Parbat is also known as the Killer Mountain due to its astonishingly high summit attempts to death ratio. Every seventh attempt to conquer the mountain results in death, according to 8000ers.com.

It is the ninth-highest peak in the world and the second-highest in Pakistan. At 8,126 metres, it is among the 14 summits that are higher than 8,000 metres.
