Two U.S. military veterans who disappeared while fighting Russia with Ukrainian forces have been released after about three months in captivity, relatives said Wednesday.

Alex Drueke, 39, and Andy Huynh, 27, went missing in the Kharkiv region of northeastern Ukraine near the Russian border June 9. Both had traveled to Ukraine on their own and became friends because both are from Alabama.

The families announced their release in a joint statement from Dianna Shaw, an aunt of Drueke.

“They are safely in the custody of the U.S. embassy in Saudi Arabia and after medical checks and debriefing they will return to the states,” the statement said.

The Saudi embassy released a statement saying it had mediated the release of 10 prisoners from Morocco, the United States, the United Kingdom, Sweden and Croatia, but there wasn’t any immediate confirmation on whether Drueke and Huynh were part of the group.

Drueke joined the Army at age 19 after the terror attacks of Sept. 11, 2001, and he believed he could help Ukrainian fighters because of his training and experience with weapons, Shaw said previously. Drueke pondered whether to go for a few weeks, she said, and then made up his mind and left in mid-April.

Huynh moved to north Alabama two years ago from his native California and lives about 120 miles (193 kilometers) from Drueke. Before leaving for Europe, Huynh told his local newspaper, The Decatur Daily, he couldn’t stop thinking about Russia’s invasion.

“I know it wasn’t my problem, but there was that gut feeling that I felt I had to do something,” Huynh told the paper. “Two weeks after the war began, it kept eating me up inside and it just felt wrong. I was losing sleep. ... All I could think about was the situation in Ukraine.”

The two men bonded over their home state and were together when their unit came under heavy fire. Relatives spoke with Drueke several times by phone while the two were being held.
