The crucial fight being slugged out between Russia, Ukraine and their allies is for the ear of US President Donald Trump, who seems increasingly frustrated with efforts to broker peace.

President Donald Trump is hoping separate phone calls Monday with Russian leader Vladimir Putin and Ukrainian President Volodymyr Zelenskyy will make progress toward a ceasefire in the war in Ukraine.

President Trump expressed his hopes for a “productive day” Monday — and a cease-fire — in a social media post over the weekend. His effort will also include calls to NATO leaders.
