Ben Stiller met with Ukraine President Volodymyr Zelenskyy as a Goodwill ambassador for the United Nations High Commissioner for Refugees on Monday to commemorate World Refugee Day.
Stiller toured occupied settlements in the Kyiv region of the war-torn country and spoke with survivors of the occupation in Irpin before meeting with Zelenskyy.
"It's one thing to see this destruction on TV or on social networks. Another thing is to see it all with your own eyes. That's a lot more shocking," Stiller said.
"What you saw in Irpin is definitely dreadful. But it is even worse to just imagine what is happening in the settlements that are still under temporary occupation in the east," Zelenskyy responded.
At one point during the meeting, Stiller told Zelenskyy, "You're my hero."
Stiller was joined by UNHCR representative in Ukraine Karolina Lindholm Billing during the visit at the president's office.
During their meeting, Zelenskyy "emphasized the violation of the rights of Ukrainians forcibly deported to Russia, including children."
The group also discussed the needs of the people displaced from their homes, including people in Poland.
"It was an honour to meet President @ZelenskyyUa on #WorldRefugeeDay as part of my visit with UNHCR @Refugees to stand in solidarity with people forced to flee in Ukraine and worldwide, and bring more attention to the humanitarian situation," Stiller tweeted to his millions of fans.
"I'm meeting people who have been impacted by war, and hearing how it's changed their lives," he said in a separate video for UNHCR.
"War and violence are devastating people all over the world. Nobody chooses to flee their home. Seeking safety is a right. And it needs to be upheld for every person."
Last week, President Joe Biden announced $1.2 billion in security and humanitarian assistance will be granted to Ukraine in the form of artillery, coastal defenses and advanced rocket systems as the deadly war with Russia continues.
The funds will also include $225 million for humanitarian aid to supply "safe drinking water, critical medical supplies and health care, food, shelter, and cash for families to purchase essential items," the White House said in a statement.
Stiller has supported UNHCR projects for years as an "advocate for the rights of refugees," and became a Goodwill Ambassador in 2018.
He's traveled to Germany, Jordan and Guatemala in support of projects, and visited Lebanon in 2018 to raise awareness for refugees involved in the Syrian conflict.
UNHCR reported Stiller has raised more than $3 million for the global organization, which was founded in 1950 and provides "vital assistance to refugees, asylum-seekers, internally displaced and stateless people."
