A building used by Boeing in Kyiv was badly damaged in a recent large-scale Russian air attack, the Financial Times reported on Sunday, citing six people familiar with the matter and photographs seen by the newspaper.

Russia launched a barrage of drones and ballistic missiles across broad swaths of Ukraine early Friday, killing at least six people and injuring dozens of others, days after Kyiv launched a daring raid on Moscow’s fleet of strategic bombers.

Ukraine said its “Operation Spiderweb” attacked Russian warplanes worth hundreds of millions of dollars, utilizing drones that each cost under $1,000 and were launched from wooden containers carried on trucks.

Russia launched one of its largest air strikes on Kyiv in over three years of war and struck a maternity ward in the southern city of Odesa, officials said.
