U.S. social media giant Meta's move to block Russian media outlets RT and Rossiya Segodnya from its platforms is "unacceptable," Kremlin spokesperson Dmitry Peskov said on Tuesday.

Peskov said that Moscow views this decision "very negatively" and has raised concerns about the company's credibility.

"Meta has discredited itself by taking these actions, and of course, such selective measures against Russian media are unacceptable," Peskov said, adding the move complicates the prospects for normalizing relations with Meta.
