American climber Alex Honnold has successfully scaled a Taiwan skyscraper without a rope, harness or safety equipment.
The building, named Taipei 101 for the number of its floors, stands at 508m (1,667ft) of steel, glass and concrete and is designed to resemble a stick of bamboo.
Honnold is renowned for being the first person to climb El Capitan, the vertical granite cliff in California's Yosemite national park - also without ropes or safety gear.
The climb was originally set to take place on Saturday but was delayed by wet weather.
His ascent in Taiwan's capital was streamed live on Netflix, which said there would be a delay on the live feed should the worst happen.
