The X account belonging to Alexei Navalny's widow Yulia has been suspended just days after it was first launched.
It is unclear why the social network, formerly Twitter, has suspended Yulia Navalnaya's account.
An online search for the account brings up the message “Account suspended” with a note that X “suspends accounts that violate our rules”.
The jailed dissident died on Friday in the Arctic prison camp where he was being held by Russian authorities.
The Kremlin’s most prominent critic, 47-year-old Mr Navalny was imprisoned in January 2021 after he returned to Russia from Germany where he was recuperating from a near-lethal poisoning with a nerve agent.
