The crew of the International Space Station have been evacuated from the US part of the satellite after an ammonia leak, according to reports.
They have been moved into the Russian part of the satellite, Russian news reports said.
All of the six crew — made up of three Russians, two Americans and one Italian — are safe in the Russian section, Russian news agencies reported.
The station is divided into two — the Russian Orbital Segment and the United States Orbital Segment (USOS), which has been evacuated.
The USOS is made and operated by Nasa, the European Space Agency, the Canadian Space Agency and the Japan Aerospace Exploration Agency.
It is run by staff in a range of mission control centers, including two in the US, and others in Germany and Japan.
New supplies arrived at the station last week, after a rocket made by SpaceX carried them there. The arrival of the supplies were delayed by a rocket explosion in October.
