The social media platform
Ms Navalnaya opened the account on Monday to announce she would continue her husband's work advocating for a free, peaceful and democratic Russia following her husband's death in a remote Arctic prison. More than 90,000 users followed the account in the first 24 hours.
But on Tuesday, the account and its activity suddenly disappeared, replaced by the words “Account suspended” and a note that X – the social media company formerly known as Twitter – “suspends accounts that violate the laws X rules.”
“Our platform's defenses against manipulation and spam incorrectly flagged @yulia_navalnaya as violating our rules,” X's security team wrote on the platform later on Tuesday. “We lifted the account suspension as soon as we became aware of the error and will update the defense.”
Earlier in the day, Ms. Navalnaya wrote on the social network Telegram that “Twitter has imposed restrictions on my account, which I opened yesterday.”
“According to the Shadowban Test service, my tweets do not appear in searches, and if you enter my name in the search bar, my page is not recommended among the recommendations,” she wrote.
After the account was restored, tens of thousands of new followers were added.
The brief suspension came shortly after Navalny's mother, Lyudmila Navalnaya, posted a video on YouTube, addressed to President Vladimir V. Putin, demanding the release of her son's body.
“I ask you, Vladimir Putin, let me finally see my son,” said Ms. Navalnaya, 69, as she stood outside the Arctic penal colony where Mr. Navalny was declared dead on Friday.
“For a fifth day I can't see him, they won't release his body to me, they won't even tell me where it is,” she said. “I demand that Aleksei's body be released immediately so that I can bury him humanely.”
Behind her, a fence topped with a coil of concertina wire marked the perimeter of the prison. The video also appears on Yulia Navalnaya's recovered X account.
On Monday, a spokeswoman for Navalny's organization said investigators had told Ms. Navalnaya that Mr. Navalny's body would not be released for at least two weeks.
On Tuesday, Russia's Interior Ministry announced it had placed Navalny's brother, Oleg, on a wanted list. Russian state news agency TASS, citing law enforcement authorities, said a new criminal case has been opened against Oleg Navalny, without specifying which law or laws he is accused of violating. However, the independent outlet Mediazona wrote on X that Oleg Navalny has been in the wanted database since 2022.
Oleg Navalny was sentenced to three and a half years in prison in 2014 on fraud charges. Critics of the Kremlin have long said the charges against him were fabricated with the aim of silencing his brother.
Oleg Navalny is believed to be living in exile outside Russia.
