Russia is open to peace with Ukraine, but achieving its goals remains a priority, Kremlin spokesman Dmitry Peskov said Sunday, days after U.S. President Donald Trump gave Moscow a 50-day deadline to agree to a ceasefire or face tougher sanctions.

In response to the escalating threat, President Trump confirmed that the U.S. will send additional Patriot air defense missiles to Ukraine. He noted that the European Union would finance the purchase of what he described as "various pieces of very sophisticated" U.S. weaponry.
