A Russian drone hit a block of flats in Romania, causing a fire and injuring two people, Romanian officials say.

Friday’s incident in the eastern town of Galați, near the border with Ukraine, was condemned by Romania’s fellow members of Nato and the EU. Ukraine said it proved again that Russia posed “a real threat” to Europe.

Romanian President Nicușor Dan said the drone was likely hit by Ukrainian air defences over Kyiv’s territory, altering its trajectory. Russian President Vladimir Putin later questioned whether the drone was Russian.

Drones fired by Russia have strayed into Romania a number of times during the four-year war with Ukraine, but it is the first time Romanians have been hurt.

Romania’s emergency situations authority said the drone’s entire explosive payload detonated and caused a fire on the 10th floor of the residential building.

Two people with abrasions required medical treatment and were taken to the Galați County Emergency Clinical Hospital. About 70 peoplewere evacuated as the fire was put out.
