Rzeszów and Lublin airports suspended operations on Sept 17 after a Russian drone crashed approximately 2 km from a Polish border crossing. Polish military aircraft scrambled into national airspace and the government issued RCB emergency alerts for the Podkarpackie and Lubelskie voivodeships during air strikes targeting Ukraine.

Moldovan authorities reported a drone entered their airspace at 08:56 from Biliaivka, Ukraine, and departed at 08:58 toward Davidove Liman. These disruptions follow a rise in daytime drone activity and air-raid alerts in western Ukraine, though the Polish military operations and territory alerts have since concluded.
