MOSCOW - Russian forces shot down all Ukrainian missiles that attempted to attack the Saky air base in Crimea, Oleg Kryuchkov, an adviser to the Russian-installed head of the local administration Sergei Aksyonov, wrote on Telegram on Thursday.

Ukraine's military said its forces had struck the Russian air base in Crimea overnight, confirming an attack that a Ukrainian intelligence source had earlier told Reuters was carried out by the SBU security service and navy using drones and Neptune cruise missiles.
