A video of two American military veterans who were kidnapped after supporting Ukrainian forces was shown on Russian television on Friday.

Andy Huynh, 27, and Alexander Drueke, 39, volunteered on Thursday to support Ukrainian soldiers in their fight against Russia’s invasion, which began in February. They were later found alive and kept hostage by the Russian military in the Donbas area, according to Russian news outlet RT.

“Mom, I just want to let you know that I’m alive, and I hope to be back home as soon as possible,” Drueke said in a video. “So, love Diesel for me. Love you.”

Following the release of the recordings, the State Department stated that authorities have viewed the images and footage of the two American citizens allegedly abducted by Russian armed personnel in Ukraine and are actively watching the situation.

President Joe Biden also made a statement on the subject, noting that he has been briefed on the missing Americans. After that, the president discouraged others from going to Ukraine to help combat the Russian invasion.

Before departing for Rehoboth, Delaware, Biden told reporters at the White House, “I have been briefed. We don’t know where they are,”

“I want to reiterate: Americans should not be going to Ukraine now. They should not be going to Ukraine.”
