Prince Harry visits war-torn Kyiv

In an unannounced trip, the Duke of Sussex arrived in Kyiv by train to meet with Ukrainian officials and medical workers.

Harry directly appealed to Vladimir Putin to 'stop this war' and condemned the systematic war crimes committed during the conflict.

His remarks about American leadership have been interpreted as a challenge to President Trump's current foreign policy.

The visit comes as Ukraine secures a massive new loan from the European Union to bolster its defenses.
