Russia and Ukraine struck each other with hundreds of drones over the weekend, forcing shutdown of airports in Moscow and throwing Russian air travel in disarray.
Russia’s defence ministry said its air defences shot down 120 Ukrainian drones during the nighttime attacks, and 39 more before 2pm Moscow time (1100 GMT) yesterday.
The Ukrainian drone attack caused flight disruptions at Moscow's Sheremetyevo and St Petersburg's main Pulkovo airports. Other airports in western and central Russia also faced disruptions.
Russia also fired large-scale drone strikes on Ukraine yesterday, injuring three civilians in Kyiv and at least two in Kharkiv, Ukraine’s second-largest city in the northeast.
The continuing onslaught comes as Ukrainian president Volodymyr Zelensky announced deals with his European allies and a leading US defence company that would allow Kyiv to scale up drone production to “hundreds of thousands” more this year.
