Wednesday's manoeuvres by Russia's strategic forces, which included a test launch of a ballistic missile from a submarine, increased worries that a nuclear weapon could be used in the conflict in Ukraine.
Vladimir Putin, the president of Russia, watched as his nuclear-armed forces practised while Moscow continued to assert, without providing any proof, that Kyiv was creating a "dirty bomb."
The Russian foreign ministry published images of purported nuclear materials on social media on Monday, claiming that they showed "Ukraine's capacities to manufacture the 'dirty bomb'."
Slovenia, though, said on Wednesday that the image was from its own nuclear waste management organisation and that it was from 2010.
It showed smoke detectors, according to Dragan Barbutovski, a counsellor to Slovenian Prime Minister Robert Golob.
Heavy fighting on the main fronts
Ukraine President Volodymyr Zelensky said fighting remained intense in the eastern Donbas region near Bakhmut, a town Russia’s elite Wagner troops have made a concerted push to seize.
“The situation on the front line hasn’t changed significantly,” Zelensky said in his daily address to the nation. “The fiercest battles are in the Donetsk region, towards Bakhmut and Avdiyivka.”
In the main southern front, Russians were apparently fortifying their positions in Kherson city as civilians were evacuating the region.
At least 70,000 people have left their homes in Kherson province in the space of a week, a Moscow-installed official, Vladimir Saldo, told a regional TV channel.
Pro-Kremlin authorities have sought to move residents to the Russian-controlled areas on the left bank of the Dnipro river, as Ukraine troops are expected to make a bid for the main urban area on the right bank.
Saldo banned entry to the right bank area of the region for a period of seven days “due to the tense situation on the contact line.”
“The Russians do appear to be digging in to defend that region,” said Pentagon spokesman Pat Ryder on Tuesday.
Submarine missile launch
Western officials downplayed the Kremlin’s war games, a regular event for which Moscow gave foreign counterparts advance warning.
“Under the leadership of… Vladimir Putin, a training session was held with ground, sea and air strategic deterrence forces, during which practical launches of ballistic and cruise missiles took place,” the Kremlin said in a statement.
Russian state-run media ran footage of a submarine crew preparing the launch of a Sineva ballistic missile from the Barents Sea in the Arctic.
The drills also included launching test missiles from the Kamchatka peninsula in the Russian Far East.
In calls to Chinese and Indian correspondents, Russia’s Defence Minister Sergei Shoigu continued to press his allegations that Ukraine planned to detonate a “dirty bomb” — a crude, small weapon filled with radioactive, biological or chemical materials — which it would blame on Russia.
Indian Defense Minister Rajnath Singh said that in his call with Shoigu, he “pointed out that the nuclear option should not be resorted to by any side as the prospect of the usage of nuclear or radiological weapons goes against the basic tenets of humanity.”
Cultural damage studied
Meanwhile, the UN culture agency UNESCO said it is using before-and-after satellite imagery to monitor the cultural destruction inflicted by Russia’s war in Ukraine and would make its tracking platform public soon.
UNESCO said it had verified damage to 207 cultural sites in Ukraine since the Russian invasion began on February 24, including religious sites, museums, buildings of historical and or artistic interest, monuments and libraries.
“Our conclusion is it’s bad, and it may continue to get even worse,” UNESCO’s cultural and emergencies director Krista Pikkat told reporters at a briefing in Geneva.
“Cultural heritage is very often collateral damage during wars but sometimes it’s specifically targeted as it’s the essence of the identity of countries,” said Pikkat.
Earlier this month, Zelensky requested that UNESCO add the historic port city of Odessa to its World Heritage List in a bid to protect it from Russian air strikes.
UNESCO is working with the Odessa authorities to make sure that its main monuments and cultural sites are marked with a blue shield — the emblem used during armed conflicts to denote a cultural property that should be protected.
