Donald Trump and Vladimir Putin hold talks in Alaska on Friday, with the U.S. president's hopes of sealing a ceasefire agreement on Ukraine uncertain but with a last gasp offer from Putin of a possible nuclear deal that could help both men save face.

The two leaders will meet in the US state later for the first time in six years - but Ukraine's Zelensky has not been invited.

Donald Trump and Vladimir Putin might be chasing different outcomes from the much anticipated Alaska summit on Friday. While the US president believes he can make a ceasefire deal with Putin, Russia's leader might have other ideas.
