Ukraine’s air force claimed that Russia hit its western part with 43 cruise and ballistic missiles as well as 74 drones.

The flurry of diplomatic activity comes as the conflict between Ukraine and Russia has intensified ahead of the inauguration of president-elect Donald Trump.

British Prime Minister Keir Starmer arrived in Ukraine Thursday, pledging to help guarantee the country’s security for a century days before Donald Trump is sworn in as U.S. president.

Sir Keir Starmer said the 100 Year Partnership would cement the friendship between the two countries for the next century.
