CNN – Actress and activist Angelina Jolie paid a surprise visit to a boarding school and medical institution in the western Ukrainian city of Lviv on Saturday, according to Maksym Kozytskyy, head of Lviv’s regional military administration.

“In one of the medical institutions, she visited children who were victims of a missile strike by the Russian army on the Kramatorsk railway station. She was very moved by their stories. One girl was even able to tell Ms. Jolie her dream privately,” Kozytsky said.

Jolie also visited a boarding school in Lviv, which became a crossing point for displaced people, humanitarian aid and weapons. She told the kids she would be back, Kozytskyy said.

At Lviv’s main train station, where Ukrainian residents regularly arrive, she spoke with volunteers who provide medical and psychological assistance.

“She thanked them for their work,” Kozytskyy said. “She spoke to people who managed to leave areas of active hostilities.”

Jolie is a United Nations special envoy for refugees, but Joung-ah Ghedini-Williams, head of global communications at the United Nations High Commissioner for Refugees, said Jolie has been to the area in a personal capacity and UNHCR was not involved in this visit.

In March, Jolie traveled to Yemen and drew parallels between the people there and those suffering because of the war in Ukraine.

Earlier on Saturday, Jolie was pictured visiting a cafe in Lviv. CNN has reached out to Jolie’s reps for comment.
