The Defense Ministry said the drone was found in a field near the village of Galti, about 2.5 kilometers (1.5 miles) southeast of the Danube River, which separates Romania from Ukraine. The drone was damaged and was not operational.
Romanian officials said they believe the drone was flying over Ukraine when it malfunctioned and crashed in Romania.
The discovery comes amid heightened tensions between Russia and NATO countries, which have accused Russia of sending troops and weapons to Ukraine. Russia has denied the allegations.
The Romanian military has increased its patrols in the area near the border with Ukraine.
Here are some additional details about the drone:
The drone is believed to be a Russian-made Orlan-10, a small, unmanned aerial vehicle that is used for reconnaissance and surveillance.
The drone is about 2 meters (6.5 feet) long and has a wingspan of about 3 meters (10 feet).
The drone is powered by a small engine and can fly for up to 12 hours.
The drone is equipped with a camera and other sensors that can be used to collect intelligence.
The discovery of the drone is a reminder of the security challenges facing Romania and other NATO countries in the wake of the Russian invasion of Ukraine.
