Russian President Vladimir Putin is ready to hold a phone call with U.S. President Donald Trump and Moscow is waiting for word from Washington that it is ready too, Kremlin spokesperson Dmitry Peskov said on Friday.

His inauguration speech was loudest in its silence on Ukraine. But hours later, US President Donald Trump laid bare – in a trademark casual, rambling fashion – his position over the war in Ukraine. And it was tougher on the Kremlin than you might expect.

Donald Trump said he would impose high tariffs and further sanctions on Russia if it continued its "ridiculous war".
