Romanian authorities said a second drone has been shot down over Romanian airspace in less than 24 hours.

The drone was intercepted by an F-16 fighter jet at around at 8:30 am on Saturday morning, roughly 10 km west of the village of Sfântu Gheorghe in the eastern part of the country, Romanian President Nicușor Dan said.

According to the Romanian Defence Ministry, radar systems had earlier picked up a drone "operating in the vicinity of the Ukrainian border."

Two F-16 fighter jets were scrambled to identify and intercept the target, with the drone "safely shot down in an unpopulated area near the border," the ministry said in a statement.

An investigation into the incident is currently underway.
