The move by social media company Twitter to ban two Russian news outlets from placing advertisements on the site is a "blatant violation" of international norms, a Russian Foreign Ministry spokeswoman said, adding that retaliation measures are unavoidable.
"We consider this a yet another aggressive step aiming to block the activity of Russian channel RT," Foreign Ministry spokeswoman Maria Zakharova said in a statement to the channel. She added that the ministry considers the move a "result of pressure from some of the US establishment and security services."
"Retaliatory measures will naturally follow," the official added.
