It is unclear why the social network, formerly Twitter, has suspended Yulia Navalnaya's account, Sky News reported.
Earlier today on her X account, Ms Navalnaya urged the Kremlin to "give back Alexei's body and let him be buried with dignity". She also said she "did not care how the killer's press secretary comments on my words".
Last night she accused Vladimir Putin of killing her husband and said evidence would be provided shortly. The Kremlin has denied involvement and said claims that the Russian leader was responsible were unacceptable.
Later X restored the social media account of Yulia Navalnaya. Less than an hour earlier X, formerly Twitter, suspended Ms Navalnaya's account.
It is still unclear why Ms Navalnaya's account was suspended. /BGNES
