Tom Ballard has been trying to conquer Nanga Parbat in the Himalayas, which is notorious for its high number of fatalities.
A British climber whose mother made history scaling Mount Everest before her death during an ill-fated expedition on K2 has disappeared on a notoriously dangerous peak in Pakistan known as Killer Mountain.
Tom Ballard, from the Peak District, is attempting to navigate the treacherous Nanga Parbat, which has been given its foreboding nickname due to the high number of fatalities among those who try to conquer it.
The 30-year-old has been climbing the 26,660ft (8,126m) mountain alongside Italian Daniele Nardi, and neither have made contact since Sunday, when they had reached a height of around 20,670ft (6,300m).
Plans for a search and rescue attempt by helicopter had to be called off due to Pakistan closing its airspace amid tensions with India. skynews
