Ukrainian First Lady Olena Zelenska sent a message to the world, and specifically the United States, through written correspondence with ABC News on Sunday.

Zelenska was unable to meet in person with the outlet or speak over the phone due to security concerns, but she wrote, “I guess my message is very similar to the one the whole world delivers. Only two simple words: STOP WAR.”

Zelenska told the outlet, “As every woman in Ukraine, now I fear for my husband.”

Ukrainian President Volodymyr Zelensky has been married to Zelenska for 18 years.

She wrote, ”Every morning before I call him, I pray everything goes well. I also know how strong and enduring he is. He is able to withstand anything, especially when he defends people and things that he loves.”

She spoke of Putin and the people supporting him in the Kremlin, discussing her doubt over “whether they have ordinary and sincere human feelings.”
