The United States assesses that Ukraine's drone attack over the weekend hit as many as 20 Russian warplanes, destroying around 10 of them, two U.S. officials told Reuters, a figure that is about half the number estimated by Ukrainian President Volodymyr Zelenskiy.

Satellite images of destroyed and damaged military aircraft on Russian bases have provided fresh detail into Ukraine’s recent unprecedented drone attack on its powerful neighbor.

New satellite images and drone footage show serious damage inflicted on aircraft at several Russian airbases during Ukraine's surprise drone strike on Sunday. The images of two Russian airbases in north-western and central Russia, taken on Wednesday morning, show 12 aircraft damaged or destroyed.
