Ukrainian President Volodymyr Zelenskyy’s most senior adviser condemned a viral video showing a Russian combat vehicle waving an American flag speeding through Ukraine’s front lines.

The footage shows an M113 armored personnel carrier, manufactured by the U.S. and captured by the Russian military, flying both Russian and American flags as it speeds through a village in Zaporizhzhia in eastern Ukraine, according to Russian state-controlled broadcaster RT.

POLITICO could not independently verify the footage or its provenance.   

“The Russians are using the symbols of the United States in their own terrorist, aggressive war,” Andriy Yermak, Zelenskyy’s right-hand man in Kyiv, fumed on Telegram. “Maximum audacity.”

The propaganda video follows Russian President Vladimir Putin’s summit with U.S. President Donald Trump in Alaska over the weekend, which was widely criticized as a publicity win for the Kremlin.

The red-carpeted affair, which saw the two leaders share an armored limousine, was Putin’s first face-to-face meeting with an American president since Moscow’s full-scale invasion began in February 2022.

Zelenskyy and a squad of European leaders are heading to the White House on Monday to meet with Trump in a bid to convince him to back a just peace deal for Ukraine, without major territorial concessions to Russia.
