Russian daredevil Alexander Remnev, in red, takes a selfie with his friend Volodya, in white, standing on the top of the 413.36-meter Princess Tower in Dubai, in this photo released on May 21, 2014. Nineteen-year-old Alexander Remnev scaled the Dubai skyscraper - before getting his camera out to take these stomach-churning pictures. Alexander, who was on holiday in Dubai with friends, said they climbed a number of the citys towering skyline during the course of their stay. [Photo/IC]
