Russian Prime Minister Dmitry Medvedev has fiercely rebuked U.S. President Donald Trump for authorizing airstrikes against a government airbase in Syria. The comment appeared on Medvedev’s Facebook page. The Moscow Times has translated the text into English:

“That’s it. The last of the campaign fog has disappeared. Instead of the theory he disseminated about working together to fight the main enemy — ISIS, the Islamic State — the Trump administration has proved that it will viciously fight the legitimate government of Syria — in blatant violation of the norms of international law, without the approval of the UN, violating [the United States’] own procedures establishing the need to notify Congress about any military operation that isn’t tied to an attack on the U.S., and on the verge of a conflict with Russia.
