Instagram has been criticised by a Russian opposition leader for giving in to pressure to block posts relating to corruption claims in the country.
It comes after Russia’s internet censor demanded that Instagram restrict access to posts connected to allegations made by Alexei Navalny, who runs an anti-corruption foundation.
Mr Navalny, who has been banned from standing against president Vladmir Putin in the country’s elections, posted a video on YouTube purporting to show billionaire Oleg Deripaska meeting with Russia’s deputy prime minister Sergei Prikhodko aboard a yacht along with women working for an escort service.
The video also claims to have proof of the pair discussing US relations – a month after Paul Manafort, at the time a Trump campaign manager, allegedly offered the oligarch private briefings on Donald Trump’s campaign.
The metals magnate has denied receiving these briefings but admitted he had hired Mr Manafort as a consultant.

Mr Deripaska won a court ruling after he claimed the video violated his right to privacy.
It led Russia’s telecom regulator Roskomnadzor to order Instagram to remove posts relating to the allegations.
The state communications oversight agency also banned Mr Navalny’s own website, Navalny.com.
Instagram, which is owned by Facebook, has now complied with demands to remove the posts about Mr Deripaska.
The watchdog acted after a court ruling last week that Mr Deripaska’s privacy rights had been violated.
Mr Navalny, who is Russia’s most prominent opposition leader, accused Instagram of giving in to an "illegal censorship request".
"Shame on you, @instagram!" he tweeted.
Roskomnadzor has said that it is still waiting for YouTube to take action against a video it wants blocked.
The 25-minute video was posted on YouTube last week and has been watched more than five million times.

The video platform had been ordered to block several clips before the end of Wednesday but has not yet taken any action.
A spokeswoman for Facebook would not discuss the specifics of the case but confirmed that it had decided to comply with Roskomnadzor’s demands.
"When governments believe that something on the internet violates their laws, they may contact companies and ask us to restrict access to that content," she told the BBC.
"We review such requests carefully in light of local laws and where appropriate, we make it unavailable in the relevant country or territory.
"We are transparent about any content restrictions we make for government requests with local law in our Transparency Report."
