A man from a celebrated family of professional daredevils has completed a tightrope walk across Niagara Falls in a televised stunt.
Nik Wallenda braved wind and heavy spray to make the 1,800ft (550m) walk from the US to Canada on a two-inch (51mm) wire.
It is the first such feat over Niagara Falls in over a century.
