Another drone may have crashed in Romania near the border with Ukraine, the country's Ministry of Defence announced on Friday.
"Fragments that could have come from a missile (drone)" had been found in an agricultural area near the city of Braila on the Danube on Thursday evening, the ministry reported. The incident is being investigated.
Braila is located 30 kilometres from the Ukrainian Danube port of Reni, which is repeatedly the target of Russian attacks. Russian drones have crashed on Romanian soil in this region several times in the past year.
The last known incident was on December 14, when Romania's Foreign Ministry summoned the Russian ambassador. NATO assumed that Russia had not intended to attack the alliance.
Romanian media reported that the suspected drone crashed near a farmhouse around 10 kilometres south-east of Braila on land between two arms of the Danube. The explosion left a crater with a diameter of 4 metres.
