Concerns about the security of dignitaries are circulating ahead of Russia’s plans for May 9 celebrations in Moscow of the 80^th anniversary of the victory over Nazi Germany, an event that leaders from Central Asia are expected to attend as the Russo-Ukrainian war continues.

The unease relates to Ukraine’s growing capacity in drone warfare, a dominant feature of the battlefield after years of war between Ukrainian troops and invading Russian forces. On Sunday, Moscow Mayor Sergei Sobyanin said air defense forces in the urban area of Podolsk, on the outskirts of Moscow, “repelled an attack” by four drones flying toward the capital.

“According to preliminary data, there is no damage or casualties at the site of the fall of the debris. Emergency services specialists are working at the scene,” Sobyanin said on Telegram.

Overnight, Ukrainian drones targeted Moscow again, disrupting operations at four of the city’s airports. Sobyanin announced on Telegram that at least 19 Ukrainian drones were intercepted. Although no significant damage or injuries were immediately reported, debris from the intercepted drones landed on a major highway.

On April 28, Russian President Vladimir Putin unilaterally declared a three-day ceasefire in the war with Ukraine from May 8 – 11 to coincide with the celebrations of victory in the Great Patriotic War, as the Soviet experience in World War II is called. But Ukraine rejected the proposal, saying it seems mainly designed to create a safe environment for its guests in Moscow and that a U.S-backed plan for a 30-day unconditional ceasefire would instead represent a serious step toward peace.

Ukrainian President Volodymyr Zelenskyy has said Ukraine isn’t responsible for anyone’s safety on Russian territory on the day of the anniversary celebrations.

Dmitry Medvedev, deputy chairman of Russia’s Security Council, has warned of massive retaliation if Ukraine strikes Moscow during the May 9 event, saying on Telegram that “in the event of a real provocation on Victory Day, no one can guarantee that May 10 will come in Kyiv.”

An analyst who tracks drone technology, Russian military weapons development and related issues said Russia’s concern about the May 9 parade stems from Ukraine’s growing expertise in drones. “Ukrainian long-range drones can already strike across the entire [of] Russia’s European (west of Urals) territory,” Samuel Bendett, a researcher at the Center for Naval Analyses, said on X.

The city of Sevastopol in Russia-controlled Crimea won’t hold a Victory Day parade for security reasons, said city Gov. Mikhail Razvozhayev, according to Russia’s state-run news agency TASS. Sevastopol hasn’t held a parade in the last couple of years because of similar concerns. In 2014, Russian forces occupied and annexed the Ukrainian territory of Crimea, where Ukraine has conducted periodic attacks with drones and other weapons since Russia’s full-scale invasion in 2022.

The Kremlin says Chinese President Xi Jinping will visit Russia at Putin’s invitation on May 7-10 and will attend the Victory Day celebrations. Russian state media have reported that the leaders of the Commonwealth of Independent States, or CIS, will also attend. The CIS, a regional group that was set up as the Soviet Union collapsed in 1991, includes the Central Asian countries that were Soviet republics: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan.

On May 3, Putin and President Shavkat Mirziyoyev of Uzbekistan discussed trade and other issues including the treatment of Uzbek migrants in Russia. A Kremlin readout of the conversation said Mirziyoyev had confirmed he “would take part in the anniversary events to be held in Moscow;” the Uzbek presidency didn’t mention the May 9 celebrations in its summary of the talk.
