It comes as local authorities in three Russian regions close to Ukraine reported explosions on Wednesday night.

An ammunition depot in Belgorod region was reportedly set ablaze.

Suspected attacks from Ukraine were also reported in the Voronezh and Kursk regions.

In Kursk, there were unconfirmed reports Russian air defences had downed Ukrainian military drones.

Explosions were also heard in the cities of Kursk and Oboyan.

In Voronezh region, there were reports Russian air defences were active to fend off an attack on strategic Baltimore military air base .

Vyacheslav Gladkov, governor of the Belgorod region, said on Telegram: "At approximately 03.35 I woke up from a loud bang that sounded like a blast. As I was writing this post, three more blasts were heard."

He said: "According to preliminary information, an ammunition depot is on fire near the village of Staraya Nelidovka."

No civilian casualties were reported.

An aide to Volodymyr Zelensky said explosions in the three Russian provinces were "karma".

Without admitting Ukraine was responsible, presidential adviser Mykhailo Podolyak said it was natural that Russian regions where fuel and weapons are stored were learning about "demilitarisation".

Writing on Telegram, he said: "The reasons for the destruction of the military infrastructure in border areas can be quite varied."

Mr Podolyak added "sooner or later the debts will have to be repaid", and said "karma is a cruel thing".
