Ukraine war must end with liberation of Crimea – Zelensky

The war in Ukraine began with Crimea and must end with its liberation, President Volodymyr Zelensky has said.

He was speaking just hours after a string of explosions hit a Russian airbase there, killing one person.

Mr Zelensky did not mention the blasts but devoted his nightly address to the peninsula, saying: "Crimea is Ukrainian and we will never give it up."

Russia has played down the explosions, and a top Ukrainian adviser denied Ukraine was responsible.

Crimea is officially part of Ukraine but was annexed by Russia in 2014 after a referendum which the international community sees as illegitimate. Many Ukrainians see this as the start of their war with Russia.

Footage on social media showed beachgoers running as the explosions hit, with witnesses saying they had heard at least 12 blasts. Crimea's Russian-appointed health department said one civilian had been killed and another eight injured.

Russia's defence ministry insisted the blasts were down to ammunition that had exploded in a store - although this has not been independently verified.

And Ukrainian presidential aide Mykhailo Podolyak denied that Ukraine was behind the blasts, telling the Dozhd online television channel: "Of course not. What do we have to do with this?"

Any attack on Crimea by Ukraine would be considered deeply serious by Moscow. Russia sounded a warning last month when ex-President Dmitry Medvedev threatened that "Judgement Day will instantly await" if Ukraine targeted Crimea.

Mr Zelensky did not refer to the blasts in his speech on Tuesday, but spoke at length about the peninsula, saying: "We will not forget that the Russian war against Ukraine began with the occupation of Crimea.

"This Russian war...began with Crimea and must end with Crimea - with its liberation," he said.

Mr Zelensky's latest remarks suggest he believes that Ukraine must retake the peninsula before the war can end - but in the past he has said different things on the issue.

If it emerges Ukraine was responsible for this attack, that would be a significant escalation. It would be the first major attack on a target inside Crimea proper.

The Ukrainians have come close: in June 2022, the Russia-appointed "leader" of Crimea said that Ukrainian forces had fired on Black Sea oil drilling platforms in Crimean waters, resulting in several casualties. And at the end of July, Russian authorities said a drone had struck a Russian naval facility in the city of Sevastopol, injuring six.

Crimea is internationally recognised as Ukrainian territory, but Russia has ruled the peninsula for eight years and Russian state structures and military facilities are very well established.

For the Kremlin, Crimea has a quasi-sacred status, seen as "historically" Russian land that Moscow "re-acquired" triumphantly in 2014. An attack so deep inside Crimean territory would be a major embarrassment for President Putin.

And there are fears that if the Ukrainians begin systematically attacking Russian targets inside Crimea, then the Russian response could be very serious indeed. Last month, former Russian President Dmitry Medvedev, now deputy chairman of the powerful Security Council, said that if Crimea were attacked, then "Judgement Day will instantly await all those [involved]. It will be very fast and very hard."

Russia annexed Crimea in March 2014, after the territory - which has a Russian-speaking majority - voted to join Russia in a referendum that Ukraine and the West deem illegal.

The vote was hastily organised after unmarked Russian troops took control of several strategic sites around the peninsula.

Earlier that year, months of pro-European protests culminated in the ousting of Ukraine's Russian-backed president.

On 24 February this year, Moscow launched a full-scale invasion of Ukraine, using Crimea as a springboard to move Russian troops deeper inside Ukraine.

Novofedorivka and Saky are about 50km (30 miles) north of the port of Sevastopol, home of Russia's Black Sea Fleet, which has been leading a blockade of the Ukrainian coastline.
