Britain’s Prince Harry has made an unannounced visit to Ukraine to express solidarity with wounded service members amid Russia’s ongoing full-scale invasion.

Harry’s representatives confirmed his arrival in Kyiv on Friday but withheld details of his schedule citing security concerns. It marks his second trip to Ukraine since 2022, following an earlier visit to Lviv in April.

“We cannot stop the war but what we can do is do everything we can to help the recovery process,” Harry told the Guardian while traveling by train to the capital.

A veteran of the British Army who served in Afghanistan, Harry is the founder of the Invictus Games — a Paralympic-style competition for injured veterans worldwide. Ukraine is currently bidding to host the games in 2029.

Earlier this week, the Archewell Foundation — established by Harry and his wife Meghan — announced a $500,000 donation to projects supporting injured children in Gaza and Ukraine. The funds will go to the World Health Organization for medical evacuations and to develop prosthetics for severely wounded youth.

According to the Guardian, Harry will meet Ukrainian Prime Minister Yulia Svyrydenko, spend time with around 200 veterans, and visit the National Museum of the History of Ukraine in the Second World War.

His trip coincides with British Foreign Secretary Yvette Cooper’s visit to Kyiv, where she unveiled new U.K. sanctions targeting Russia’s oil revenues and military supplies.

Harry’s appearance in Ukraine follows a four-day stay in the U.K., where he met his father, King Charles III, for the first time in 19 months — a move seen as a step toward mending strained royal ties.

The visit comes less than a week after Russia launched its largest aerial assault on Ukraine since the 2022 invasion.
