Ukraine launched a wave of drone attacks on Russia early Wednesday, likely Kyiv's most extensive assault on Russian soil since the 18-month conflict between the two countries began.
The Ukrainian drones were aimed at six Russian regions, with one of them hitting an airport near Russia's border with Estonia and Latvia. That drone ignited a huge blaze and damaged four Il-76 military transport planes, which can carry heavy machinery and troops, the Russian news agency Tass reported, quoting emergency officials.
