Volodymyr Zelensky has revealed Ukraine has successfully combat tested its new domestically-produced Long Neptune missile with a range of 621 miles.

This puts Russian capital Moscow within its range with Zelensky saying that Kyiv has had 'significant results' on its missile programme aimed at providing its own security against the threat of Vladimir Putin.

'Long Neptune has been tested and successfully used in combat,' he said.

'A new Ukrainian missile, an accurate strike. The range is a thousand kilometres [621 miles].

'Thank you to our Ukrainian developers, manufacturers and military. We continue to work to guarantee Ukrainian security.'

Ukrainian Telegram channel Exilenova+ suggested that Friday's dramatic strike at Tuapse Oil refinery may have been by the new Neptune, which is a development of the earlier version of the weapon which sank Putin's Black Sea Fleet flagship, Moskva in 2022.

'There is an assumption that it was [the new] Neptune,' said the channel.

Ten explosions were heard when the strike came. However, there was no official confirmation, and a missile - rather than long-range drone - strike might have caused far more mayhem.

Yet the Tuapse refinery, a key supplier to the Russian military machine, was still burning 36 hours after it was hit, as seen in dramatic footage.

The refinery is just 55 miles from Putin's £1 billion clifftop palace at Gelendzhik on the Black Sea, and the strike was a warning to him.

Another devastating hit came on Friday when Ukraine flattened the local history museum in Sudzha soon after the Kursk region town fell back in Russian hands.

It was not clear if this may have been a Long Neptune strike.

But there was also a claim in January that the new version of Neptune had destroyed a major Russian drone warehouse in the village of Chaltyr, in Rostov region, triggering a giant fireball.
