"All assigned targets have been destroyed," the Russian defence ministry said, adding that its forces hit "a significant stock of weapons and ammunition of the Ukrainian armed forces."

Russia did not specify which targets had been hit, only saying it aimed at "large depots of foreign weapons and equipment as well as enemy reserves."

Ukraine said that Russian forces had launched 30 cruise missiles from land, sea and air, targeting several regions and killing one person in the southern port city of Odesa.

Russian strikes on Kyiv have reached an intensity not seen since a wave of attacks started last autumn.
