WRAPUP 10-Blasts at Russian base in Crimea show possible Ukrainian fightback

Moscow denounced sabotage and Ukraine hinted at responsibility for new explosions on Tuesday at a military base in the Russian-annexed Crimea region that is an important supply line for Russia's invasion of Ukraine. The blasts engulfed an ammunition depot at a Russian military base in the north of the peninsula, disrupting trains and forcing the evacuation of 2,000 people from a nearby village, according to Russian officials and news agencies.

Plumes of smoke were later seen at a second Russian military base in central Crimea, Russia's Kommersant newspaper said, while blasts hit another facility in the west last week. The explosions raised the prospect of new dynamics in the six-month-old war if Ukraine now has capability to strike deeper into Russian territory or pro-Kyiv groups are having success with guerrilla-style attacks.

Russia has used Crimea, which it annexed from Ukraine in 2014, to reinforce its troops fighting in other parts of Ukraine with military hardware, a process Kyiv is keen to disrupt ahead of a potential counter-offensive in southern Ukraine. Crimea is the base of Russia's Black Sea Fleet and also popular in the summer as a holiday resort.

In Tuesday's incident, an electricity substation also caught fire, according to footage on Russian state TV. Russia's RIA news agency said seven trains were delayed and that rail traffic on part of the line in northern Crimea had been suspended. OPERATION 'DEMILITARISATION'

Ukraine has not officially confirmed or denied responsibility for explosions in Crimea, though its officials have openly cheered incidents in territory that, until last week, appeared safe in Moscow's grip beyond range of attack. After Tuesday's blasts, Ukrainian presidential adviser Mykhailo Podolyak and chief of staff Andriy Yermak both exulted on social media at "demilitarisation": an apparent mocking reference to the word Russia uses to justify its invasion.

"Operation 'demilitarisation' in the precise style of the Armed Forces of Ukraine will continue until the complete de-occupation of Ukraine's territories. Our soldiers are the best sponsors of a good mood," Yermak wrote on Telegram. Russia's defence ministry said the explosions at the ammunition depot were "a result of sabotage".

With the war raging since Feb. 24, attention has also focused in recent days on shelling in the vicinity of the Zaporizhzhia nuclear reactor complex, Europe's largest, in a Russian-occupied area of southern Ukraine. Russian-installed officials there, quoted by Interfax news agency, said on Tuesday Ukrainian forces were shelling the city of Enerhodar where the plant is located. They accused Ukraine of doing so to provoke Russia into returning fire.

The Ukrainian side did not immediately respond to a Reuters request for comment. Reuters could not immediately verify the latest shelling reports. Each side has blamed the other for heightened risks to Zaporizhzhia, which Russia seized in March though Ukrainian technicians continue to operate it.

The region's governor, Oleksandr Starukh, said up to 400,000 people would need to be evacuated in the event of an accident, and U.N. Secretary General Antonio Guterres has called for the area around the plant to be demilitarised. Meanwhile, Russia's FSB security service accused Ukrainian "saboteurs" of repeatedly blowing up electricity pylons running from a nuclear power station in the Kursk region, some 90 km (55 miles) north of the Ukraine border, disrupting plant operations.

Reuters was not able to immediately verify the report. Ukraine's defence ministry did not immediately respond to a request for comment. The Ukraine conflict has caused millions to flee, killed thousands and deepened a geopolitical rift between Moscow and the West.

Moscow calls its invasion a "special military operation" to demilitarise its neighbour, protect Russian-speaking communities and push back against the NATO military alliance's enlargement with member states closer to Russia. Ukraine, which was part of the Russian-dominated Soviet Union until its 1991 break-up, accuses Moscow of waging an imperial-style war of conquest.

PUTIN DENOUNCES U.S. In a speech to a security conference, Russian President Vladimir Putin accused the United States of trying to drag out the Ukraine war by backing Zelenskiy's government while also whipping up frictions in Asia.

He cited the AUKUS security pact between Australia, Britain and the United States as evidence of Western attempts to build a NATO-style bloc in the Asia-Pacific region. U.S. House Speaker Nancy Pelosi's visit this month to Taiwan, which China claims as its own, was "part of a purposeful, conscious U.S. strategy to destabilise and sow chaos in the region and the world", Putin said.

Even as the biggest attack on a European state since 1945 ground on, there was further progress on a grain deal to ease a global food crisis created by slumping Ukrainian exports. Following the unblocking of ports, the ship Brave Commander carried the first cargo of food aid for Africa from Ukraine since Russia's invasion.

Ukraine can export 3 million tonnes of grain from its ports in September and may eventually be able to export 4 million tonnes monthly, a government official said.
