The move means Trump is walking back the 50-day deadline he set this month in response to Russia's continued bombing of Ukrainian cities.

On Monday, Mr Trump abruptly shortened a previously announced 50-day ultimatum to just 10 days, warning President Vladimir Putin that unless attacks on civilians stop by August 8, the US will hit Russia with fresh sanctions and tariffs.

U.S. President Donald Trump has made clear that he wants a deal to end Russia’s war in Ukraine by August 8, the United States told the United Nations Security Council on Thursday.
