Ukrainian air defenses repelled a wave of Russian strikes in Kyiv on Wednesday, knocking at least 13 drones out of the sky, with explosions reported in the historical center of the city.

Russia has increasingly reverted to the use of its Iranian-made drones after receiving what was likely a new shipment of them earlier this month. Even after Ukraine shot down the first shipment, Iranian officials were carrying out training on their Mohajer and Shahed 136-series drones in Crimea, Ukrainian officials said.
