Soyuz capsule lands safely after failure to undock

The delayed Soyuz capsule carrying a US astronaut and two Russian cosmonauts has landed safely in Kazakhstan.

Officials said the capsule had landed upright almost exactly on target in Northern Kazakhstan at 1123 local time.

The Soyuz had earlier undocked from the International Space Station after a failed attempt on Friday.

America's Tracy Caldwell-Dyson and Russia's Alexander Skvortsov and Mikhail Kornienko were on board the space station for almost six months.
