Nato chief Mark Rutte said on Friday he had assured Romania’s president of the alliance’s “absolute solidarity” as he slammed Russia for a drone crash in the country bordering Ukraine. Nato member Romania said that a drone injured two people in a southeastern city during an overnight Russian attack on Ukraine , the first time in the war that a drone had hit a densely populated area in Romania and caused injuries. The incident in Romania, also a member of the European Union, was likely to increase tensions on Nato’s eastern flank at a time when Ukraine’s allies are worried about Russia’s war on its neighbour spilling over its borders.
