Russia thwarted an attack by 20 Ukrainian drones targeting Moscow-annexed Crimea overnight, the Russian Defence Ministry said on Saturday. Fourteen drones were shot down by Russian air defences and a further six were jammed electronically, the ministry said in a Telegram post. No casualties or damage were reported.

Kyiv officials neither confirmed nor denied Ukraine’s involvement in the attacks. The overnight attacks followed three consecutive days of drone attacks on the Russian capital, Moscow. Firing drones at Russia, after more than 17 months of war, has little apparent military value for Ukraine but the strategy has served to unsettle Russians and bring home to them the conflict’s consequences.
