Explosions have been reported overnight near the Russian port of Novorossiysk on the Black Sea.

Footage shared on social media on Friday appeared to show loud blasts at the port, which is a major hub for Russian exports.

Russia’s defence ministry said it had repelled a Ukrainian attack on its naval base there with two sea drones.

It said the drones had been spotted and destroyed by Russian ships guarding the outer harbour of the naval base.
