The Polish foreign minister said he could not guarantee that Russian President Vladimir Putin's plane would not be forced to land.

The Kremlin denied Tuesday that it was holding up President Donald Trump’s latest push to end the war in Ukraine, and insisted it had not changed its demands ahead of possible talks. Trump had announced that Russia and the United States' top diplomats would meet this week, with his own summit with Vladimir Putin to follow in Budapest, Hungary.

WASHINGTON (AP) — Plans are on hold for President Donald Trump to sit down with Russian leader Vladimir Putin to talk about resolving the war in Ukraine, a U.S. official said Tuesday. The meeting had been announced last week. It was supposed to take place in Budapest, although a date had not been set.

The back-and-forth was the latest example of President Trump teasing a breakthrough, only to be pulled back by President Vladimir V. Putin of Russia.

Kremlin envoy Kirill Dmitriev floated the tunnel idea late on Thursday after Putin spoke to Trump by phone and agreed to meet in Budapest.

Donald Trump urged Volodymyr Zelenskyy to accept Russia’s terms for ending its war in a volatile White House meeting on Friday, warning that Vladimir Putin had said he would “destroy” Ukraine if it did not agree.

A weekend call between President Donald Trump and Ukrainian President Volodymyr Zelenskyy devolved into a "shouting match," and Russian state media pundits are now declaring it the result of Russian President Vladimir Putin's influence over Trump.

The denial came after a Financial Times report described a closed-door meeting at the White House that allegedly devolved into a “shouting match."
