Twitter acknowledged Wednesday it suspended in error some accounts relaying information about Russian military movements as the threat builds for an attack on Ukraine.
The social network has begun restoring access to the users, which were taken down due to "our work to proactively address manipulated media," tweeted the platform's head of site integrity Yoel Roth.
A company spokesperson said earlier claims that the accounts were taken offline by a coordinated campaign or mass complaints were untrue.
"We took enforcement action on a number of accounts in error," the spokesperson added. "We're expeditiously reviewing these actions and have already proactively reinstated access to a number of affected accounts."
Like Facebook and YouTube, the platform is regularly accused of not doing enough to fight misinformation.
But Twitter has fewer human and financial resources than its Silicon Valley neighbours to curb the harmful phenomenon.
