The Russian military is ready to carry out an offensive against the Crimean peninsula in Ukraine, but military experts argue that it is actually running out of ammunition.
"Everything is going according to plan," the Kremlin-appointed head of the region, Sergei Aksyonov, assured the state news agency Ria Novosti in an interview.
Russia illegally annexed Crimea in 2014, before mounting its full-scale invasion of Ukraine last year.
Aksyonov said satellite images showed extended fortification lines on the isthmus to the peninsula and that trenches had already been dug on the beaches. Russian forces "are proceeding untypically, asymmetrically," he said, without elaborating.
His comments came as military experts said Russia is running out of missiles and its efforts to conquer Ukraine are likely to be seriously hampered by a lack of ammunition.
The assessment came from the British Defence Ministry's daily intelligence update on Friday.
The report said Russia now needs to accumulate a critical mass of newly manufactured missiles directly from the industry before it has the means for a strike large enough to overwhelm Ukrainian air defenses.
The ministry predicted that the frequency of Russian missile attacks on Ukraine is likely to decrease because of the missile problem.
The supply issue is also likely to affect Russian attempts to resume its military offensive, the Washington-based Institute for the Study of War wrote in a report published on Thursday.
It said Russian forces may be preparing to resume an offensive around the frontline town of Wuhledar in eastern Ukraine, as indicated by the exchange or relocation of troops in the Donbass region.
However, an elite Russian unit of naval infantrymen suffered significant casualties when they attempted to take the Wuhledar area in a three-week offensive in February and the troops have been already re-formed at least seven times, the think tank wrote.
Ammunition is also an issue on the Ukrainian side. The country needs two more months to build up reserves for its planned spring offensive, Mykhailo Podolyak, an adviser to the presidential office in Kyiv, told the Italian newspaper La Stampa. "We need to increase the supply of heavy artillery shells of 155-millimeter caliber and long-range missiles," he said.
Independent military experts had previously mentioned an earlier date for a possible counter-attack by Kyiv. Podolyak put the need for armored vehicles to liberate more occupied territories at 400 to 500, a similar figure given in the past by Commander-in-Chief Valerii Zaluzhnyi. In addition, according to Podolyak, fighter planes are needed to intercept ballistic missiles and control airspace.
He made no statement on the thrust of the planned counter-offensive but said Russia has few options for its own offensive actions. "Active enemy offensive actions will continue in the direction of Bakhmut, Wuhledar, Lyman and Soledar," Podolyak predicted.
The military news came as Finnish Prime Minister Sanna Marin visited the Ukrainian capital Kyiv on Friday. She and Ukrainian President Volodymyr Zelenskyy attended a memorial service for a soldier killed in the still heavily-contested eastern Ukrainian town of Bakhmut.
On Thursday Zelenskyy condemned the widespread Russian missile attacks on Ukraine's energy infrastructure and called for further actions against Russia during his nightly video address. He criticized the fact that a missile strike had once again temporarily cut off the power supply to the Russian-occupied nuclear power plant in Zaporizhzhya.
Russia could therefore no longer be a reliable partner in the nuclear sphere, he said. "This means that the sooner Russia's nuclear industry is the target of sanctions, the safer the world will be. A terrorist state cannot be allowed to use nuclear facilities anywhere in the world for terror," Zelenskyy remarked.
