Russian cosmonauts have arrived at the International Space Station wearing Ukrainian colours, in what may be a statement opposing the invasion.

The three men were the first new arrivals since Russia attacked its eastern neighbour last month.
They were warmly welcomed on board, hugging and greeting their fellow American, Russian and German crew.

The ISS is a joint project between Russia, America, Canada, Japan and several European countries.
It is led by a US-Russian partnership that has continued for two decades despite fluctuating tensions between the two world powers.
Russian cosmonauts Denis Matveyev, Oleg Artemyev and Sergey Korsakov docked at the ISS after a three-hour flight which blasted off from a Russian-owned facility in Kazakhstan.
"Congratulations on the successful docking," a voice from Russia's mission control said moments later.
A few hours later, two sets of hatches were opened and the three smiling men floated into the space station one by one wearing bright yellow space suits with blue accents.

The standard-issue Russian uniform is plain blue, and at least one of the men was seen wearing this before take-off.
The moment was live-streamed by both Nasa, the American space agency, and the Russian agency Roscosmos.
"It became our turn to pick a colour," Artemyev said when he was asked about the suits in a live-streamed press conference.
"We had accumulated a lot of yellow material so we needed to use it," he joked. "That's why we had to wear yellow."
Since the invasion of Ukraine, people around the world have used the colours of its national flag to show solidarity and support.
But Russia's space agency denied that the cosmonauts were showing support for Ukraine.
"Sometimes yellow is just yellow," Roscosmos's press service said on its Telegram channel.
"The flight suits of the new crew are made in the colours of the emblem of the Bauman Moscow State Technical University, which all three cosmonauts graduated from...To see the Ukrainian flag everywhere and in everything is crazy."
The three Russians will begin a science mission on the ISS that is set to last just over six months.
They will replace three current crew members who are scheduled to fly back to Earth on 30 March.
