Ukrainian President Volodymyr Zelenskiy won diplomatic backing from Europe and the NATO alliance on Sunday ahead of a Russia-U.S. summit this week where Kyiv fears President Vladimir Putin and President Donald Trump may try to dictate terms for ending the 3-1/2-year war, Reuters reported.

Trump, who for weeks had been threatening new sanctions against Russia for failing to halt the war, announced instead on Friday that he would meet Putin on August 15 in Alaska.

A White House official has said Trump is open to Zelenskiy attending but preparations are underway for only a bilateral meeting.

Russian strikes injured at least 12 in Ukraine's Zaporizhzhia region, the country's foreign affairs ministry said on Sunday, according to Reuters.
