Moldovan Ministry of Defence officials detected an unauthorized aerial object crossing the state border at 12:34 on Sept. 21 from the direction of Mayaki in Ukraine's Odesa region. The object entered toward the village of Palanka in the Stefan Voda district and returned to Ukraine at 12:36. A second drone violation occurred after midnight, originating from the Vinnytsia region.

The Air Operations Service tracked the overnight aircraft starting at 00:17, observing it move toward the Transnistrian segment before it disappeared from surveillance at 00:44 near Tabani in the Briceni district. Moldova restricted airspace in the northern part of the country for 24 minutes and deployed military reconnaissance teams to investigate the terrain. Both incursions happened during Russian large-scale attacks on Ukraine.
