NATO member Romania said it had found fragments of what appeared to be a drone on a farm near the Danube River and the border with Ukraine late on Thursday, according to 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.”
According to AP News, the Ministry of Defence did not provide additional details, although since the start of the full-scale invasion of neighboring Ukraine, Romania has confirmed drone fragments on its territory on several occasions.
NATO has a mutual defence commitment if one of its members comes under attack, but the Atlantic alliance and Romanian officials have said following similar such incidents in the past that they have found no evidence of any deliberate attack targeting Romania.
On Sunday a Russian missile entered the airspace of Poland, also a member of the NATO alliance.
Warsaw said early on Friday that it had scrambled jets due to Russian missile strikes on Ukraine.
Moscow launched a large-scale attack on Ukraine’s energy infrastructure Friday, with a mass barrage of 99 drones and missiles hitting regions across the country, Ukraine’s armed forces said, according to AP News.
Air raid warnings across the country continued through the night as the strike targeted 10 separate regions, Ukraine’s Interior Minister, Ihor Klymenko, said in a statement on Telegram.
The Ukrainian air force reported that 60 Shahed drones and 39 missiles of varying types were seen across the country, of which 58 drones and 26 missiles were ultimately shot down by air defenses.
