NATO member Romania said it had found fragments of what appeared to be a drone on a farm near the river Danube and the border with Ukraine late on Thursday, APA reports citing Reuters.
Russia has been striking targets in western and central Ukraine with missile and drone attacks conducted at night.
"In the evening of March 28, 2024, fragments that seem to come from an aerial device (drone) were identified on an agricultural land in Insula Mare a Brailei," Romania's defence ministry said in a statement.
"The Ministry of National Defence, together with specialized structures within the National Defence System, public order and national security, is conducting an investigation of the incident."
