Ukraine launched one of its largest aerial attacks of the war on Russia overnight into Sunday, sending hundreds of drones toward Moscow as Russian forces answered with ballistic missiles and drones on Kyiv — a bloody exchange that also spilled into NATO airspace when Spanish fighter jets shot down a suspected Russian drone over Romania.

Moscow Mayor Sergei Sobyanin said the capital was targeted by roughly 600 drones, with defenses destroying 201 of them over the Moscow region alone. Russia's Ministry of Defence claimed its forces downed 822 Ukrainian drones nationwide overnight. Russian state media outlet TASS called it the largest Ukrainian drone attack on the country since the start of the year, with many drones aimed squarely at the capital region, where much of Russia's political and business elite lives.

The barrage killed at least six people inside Russia: an 83-year-old man died when a drone struck a private home in the Moscow region, and five more were killed in strikes on the southern Rostov region, which borders Ukraine. Ukraine's military said one target hit in Rostov was a defense-industrial plant that manufactures solid rocket propellant. In Podolsk, outside Moscow, a Wildberries warehouse — part of Russia's largest online retailer — was set ablaze, sending up thick black smoke.

Kyiv Under Fire in Return

Russia hit back with ballistic missiles and drones on Kyiv, Kremenchuk and Kryvyi Rih. Al Jazeera reported a woman was killed in the Kyiv strikes, which also destroyed a popular outdoor book market in the capital and sparked fires across the city. Ukraine's Air Force said the assault involved 106 drones alongside the missiles.

"WHEREVER THE RUSSIANS CAN REACH WITH BALLISTIC MISSILES, THEY STRIKE CIVILIAN INFRASTRUCTURE."

That was Ukrainian President Volodymyr Zelenskyy's assessment of the strikes, framing the attack as further evidence that Moscow continues targeting non-military sites nearly four and a half years into its full-scale invasion.

The exchange rattled NATO's eastern flank hours later. Romania's Ministry of National Defence said two Spanish F-18 jets, flying a NATO air-policing mission, scrambled after a drone entered Romanian airspace near the Moldovan border at 4:44 a.m. local time. The jets intercepted and destroyed the drone at 5:01 a.m. over an unpopulated area of Galați County. Officials said the drone appeared to be Russian in origin and had crossed into Romania from Moldova — the fourth such incursion into Romanian airspace this year, according to UPI.

An Escalating Pattern

Sunday's clash is the latest sign that both sides are widening the range and scale of long-distance strikes. Ukraine has increasingly targeted Russian energy infrastructure, defense manufacturing and logistics hubs deep inside Russian territory this year, while Russia has kept up missile and drone bombardment of Ukrainian cities despite repeated diplomatic pushes for a ceasefire. Drone incursions into NATO territory — Romania, Poland, Bulgaria and Germany have all reported incidents in recent months — have added a new layer of alarm for the alliance, which has responded by intercepting stray drones rather than escalating further.

No immediate ceasefire talks were announced Sunday. Romanian officials have previously summoned Russia's envoy after similar airspace violations, and a similar diplomatic protest is expected in the coming days. Both Kyiv and Moscow are likely to keep trading long-range strikes as the war grinds toward its fifth year with no resolution in sight.
