A Russian space capsule has undocked from the International Space Station (ISS) to take three astronauts back to Earth – two of them having completed a record-long stay on the orbiting laboratory.

The capsule carrying Russians Oleg Kononenko and Nikolai Chub and American Tracy Dyson is expected to land in the vast Kazakhstan steppe about three and a half hours after the undocking.
