Nasa astronaut Suni Williams, one of two astronauts stuck on the International Space Station, has completed her first spacewalk since arriving.

One of the two astronauts stranded at the International Space Station (ISS) has taken their first space walk since arriving at the station nearly seven months ago.

Suni Williams and Butch Wilmore launched aboard Boeing's new Starliner capsule last June on what should have been a weeklong test flight. They've been in space ever since.
