European Commission President Ursula von der Leyen said on Friday Russia had "crossed yet another line" after one of its drones hit a densely populated area in Romania and injured civilians during an overnight attack in neighboring Ukraine. "We stand in full solidarity with Romania and its people," von der Leyen said in a post on X. "As we continue strengthening our security and deterrence, especially on our eastern border, we will keep increasing the pressure on Russia." A Russian drone wounded two people as it struck an apartment building in NATO-member Romania, its defense ministry said on Friday, the latest spillover from the four-year war into neighboring states. NATO-member nations that border the warring sides are facing increasing risks as overnight air barrages intensify, with Latvia's government collapsing in recent weeks due to scrutiny of its defense capacities following a stray Ukrainian drone incursion.
