Lviv, in western Ukraine, has been under attack from the Russian army in recent weeks and earlier this month, a missile attack on the city left at least seven people dead.
In February, Jolie spoke about the war in Ukraine in a post to her 12.7 million Instagram followers.
She wrote: "Like many of you, I'm praying for the people in Ukraine.
"My focus along with my @refugees colleagues is that everything possible is done to ensure the protection and basic human rights of those displaced, and refugees in the region.
"We have already seen reports of casualties and people starting to flee their homes to seek safety.
"It is too soon to know what will happen, but the significance of this moment – for the people of Ukraine, and for the international rule of law – cannot be overstated."
