Residents in the southern Russian city of Rostov-on-Don react, as Moscow claims to have shot down a Ukrainian drone, causing it to crash in the city's historic centre, not far from military headquarters. Images show the windows and door of a small, old two-storey building blown out from the impact and damages to several cars parked nearby. "There were two blasts within 15 minutes, they were powerful," Vladimir, a 68-year-old retiree in Rostov-on Don, tells AFP. IMAGES AND SOUNDBITES
