An American teenager has become the youngest person to climb to the summit of the tallest mountains on each of the seven continents.
Jordan Romero, 15, reached the summit of Mt Vinson Massif in Antarctica, the last peak in a quest he started six years ago.
His team includes his father and stepmother, the BBC reports.
At 10 years old, Jordan climbed Mt Kilimanjaro in Africa and at 13, the Californian climbed the world's highest mountain, Mt Everest.
The other peaks the teenager climbed are: Russia's Mt Elbrus (July 2007), Argentina's Mt Aconcagua (December 2007), Mt McKinley in the US (June 2008) and Indonesia's Carstensz Pyramid (September 2009).
