Britain said on Tuesday that Russia's Black Sea Fleet is struggling to exercise effective sea control, with patrols generally limited to the waters within sight of the Crimean coast.
The Black Sea Fleet continues to use long-range cruise missiles to support ground offensives but is keeping a defensive posture, the British Defencs Ministry said in its daily intelligence bulletin on Twitter.
The Black Fleet's limited effectiveness undermines Russia's overall invasion strategy, in part because the amphibious threat to Odesa has now been largely neutralized, the intelligence update added.
Ukraine stopped short of publicly claiming responsibility for the Crimean depot blasts or for those that destroyed nine Russian planes at a Crimean air base last week.
But in his video address Tuesday night, Ukrainian President Volodymyr Zelenskyy warned people to avoid Russian military installations and storage sites for ammunition and equipment. He said the explosions could have a number of causes, including incompetence.
"But they all mean the same thing: the destruction of the occupiers' logistics, their ammunition, military and other equipment, and command posts, saves the lives of our people," he said.
Russia seized the Crimean Peninsula in 2014 and has used it to launch attacks against Ukraine in the war that began nearly six months ago.
Russia on Tuesday blamed saboteurs for orchestrating a series of explosions at an ammunition depot in Russian-annexed Crimea, a rare admission that armed groups loyal to Ukraine are damaging military logistics and supply lines on territory it controls, Reuters reported.
The incident follows a series of explosions last week at a Russian-operated air base in Crimea, which Ukrainian officials hinted were part of some kind of special operation but which Moscow said at the time was an accident.
Ukraine can export 3 million metric tons of grain from its ports in September and may in the future be able to export 4 million metric tons from them monthly, Deputy Infrastructure Minister Yuriy Vaskov said on Tuesday, according to Reuters.
He said Ukraine had received applications for 30 ships to come to Ukraine in the next two weeks to export grain.
Ukraine's grain exports slumped since Russia invaded on February 24 and blockaded Ukrainian Black Sea ports, but three Black Sea ports were unblocked last month under a deal between Moscow and Kyiv that made it possible to send hundreds of thousands of metric tons of Ukrainian grain to buyers.
Estonia this week will close its border to more than 50,000 Russians with previously issued visas, the first country in the European Union to do so, making it harder for ordinary Russians to enter EU, .
Like many of the hundreds of Russians crossing the border each day at the Estonian town Narva, Anna is worried she will not be able to keep coming to Estonia, where she visits the graves of relatives.
The ban comes just four days after Ukrainian President Volodymyr Zelenskiy issued a fresh call for EU states to ban visas for Russian nationals to keep the bloc from becoming a "supermarket" open to anyone with the means to enter.
With much fanfare, ship after ship loaded with grain has sailed from Ukraine after being stuck in the country’s Black Sea ports for nearly six months. More quietly, a parallel wartime deal met Moscow’s demands to clear the way for its wheat to get to the world, too, boosting an industry vital to Russia’s economy that had been ensnared in wider sanctions,
While the U.S. and its European allies work to crush Russia’s finances with a web of penalties for invading Ukraine, they have avoided directly sanctioning grains and other goods that feed people worldwide.
Russian and Ukrainian wheat, barley, corn and sunflower oil are important to countries in Asia, Africa and the Middle East, where millions rely on subsidized bread for survival. As the war spiked food and energy prices, millions of people have been pushed into poverty or closer to the brink of starvation.
Germany has deployed troops with the EU's peacekeeping mission in Bosnia for the first time in a decade as concerns mount about instability from the Ukraine war spilling over to the Western Balkans, .
On Tuesday, the first German troops to return to the country were greeted in a ceremony at the Sarajevo headquarters of the EUFOR force that marked the start of their mission, a German military spokesman said.
Germany will deploy some 30 troops in total to Bosnia by mid-September, returning to the force that it had left at the end of 2012.
