Romania’s president said Wednesday parts of a Russian drone were found on its territory near the Danube River following a Russian assault on a Ukrainian port earlier this week. President Klaus Iohannis said Romania remains “on alert” after the attack and is in contact with its NATO allies.

President Klaus Iohannis: “If it is confirmed that these elements belong to a Russian drone, such a situation would be completely inadmissible and a serious violation of the sovereignty and territorial integrity of Romania, a NATO ally.”
