Two American veterans from Alabama who went to Ukraine to help fight against the Russian invasion are missing and feared to have been captured by Russian-backed separatists, their family members said.

The U.S. State Department is looking into reports that Andy Tai Ngoc Huynh, 27, of Trinity, Alabama, and Alexander Drueke, 39, of Tuscaloosa, Alabama, haven’t been heard from for days after being in the Kharkiv region of northeastern Ukraine, near the Russian border.

The news comes as Russia has advanced in its attempts to overtake Sievierodonetsk in the Donbas region, stepping up its attempts to take out Ukraine’s supplies.

On Wednesday, Russia said its forces destroyed a depot where NATO-supplied weapons were stored in Ukraine in the Lviv region. Russian Defense Ministry spokesman Igor Konashenkov said high-precision missiles were used to target the depot, where weapons including U.S.-supplied shells for M777 howitzers were being kept.

Ukraine officials didn’t immediately comment on the strike near the town of Zolochiv.

The governor of Luhansk, Serhiy Haidia, also told The Associated Press that the situation in Sievierodonetsk is getting worse, because Russian forces have more manpower and weapons, “but our military is holding back the enemy from three sides at once.”
