Pro-Russian separatists in Ukraine detained a 35-year-old US Air Force veteran. He is the fourth known American veteran to be held captive.

Suedi Murekezi contacted his brother, Sele, on July 7, informing him that he had been falsely accused of being part of a pro-Ukraine protest and had been taken prisoner.

Suedi said he is being detained in the Donetsk People’s Republic (DPR) along with two other American detainees, Alexander Drueke and Andy Tai Huynh.

Soon after receiving the call, Sele reached out to US officials at the embassy in Kyiv to ask for help.

“He has done his part for America,” Sele told the Washington Post, “and maybe America can do something for him.”

Murekezi moved to the US from his native Rwanda when he was a teenager, Sele shared. His brother then moved to Ukraine in 2018 to work in the country’s dynamic technology sector, eventually settling in Kherson.

Kherson was among the first major regions to fall to Russian troops shortly after the February 24 invasion.

When tensions between Russia and Ukraine were starting to escalate, Sele advised his brother to leave the country but the latter refused.
