A Russian fighter jet Tuesday, Marc 14, 2023, struck the propeller of a U.S. MQ-9 drone surveillance drone over the Black Sea, causing American forces to bring down the unmanned aerial vehicle in international waters, the U.S. military said, an incident that highlighted soaring U.S.-Russian tensions over Moscow's war in Ukraine.
