Two NATO members said that Russian drones have violated their airspace, as one reportedly flew into Romania during nighttime attacks on neighboring Ukraine while another crashed in eastern Latvia the previous day.

A drone entered Romanian territory early Sunday as Moscow struck "civilian targets and port infrastructure" across the Danube in Ukraine, Romania's Ministry of National Defense reported. It added that Bucharest had deployed F-16 warplanes to monitor its airspace and issued text alerts to residents of two eastern regions.
