Sunday marked the 40th anniversary of the catastrophic 1986 Chernobyl nuclear explosion – the worst civilian nuclear disaster in recorded history – and Ukraine’s commemoration was overshadowed by a fresh wave of deadly Russian drone strikes that left multiple casualties on both sides of the frontline. In this charged context, Ukrainian President Volodymyr Zelensky issued a stark condemnation of Moscow, accusing it of engaging in deliberate nuclear terrorism.
The 1986 Chernobyl disaster permanently altered global attitudes toward nuclear power, leaving a contested and grim human toll in its wake. While a 2005 United Nations report estimated that up to 4,000 people across the three most affected regions would die from radiation-related causes, environmental advocacy group Greenpeace placed the projected death toll far higher, at nearly 100,000. Around 600,000 first responders and cleanup workers, known locally as “liquidators”, were exposed to dangerously high levels of radiation while containing the disaster after the explosion. To honor the victims of the 1986 catastrophe, members of the public gathered in the Ukrainian town of Slavutych on Sunday, lighting candles arranged in the shape of a radiation warning symbol outside a memorial for those who lost their lives.
In a social media statement released to mark the somber anniversary, Zelensky argued that Russia’s full-scale invasion of Ukraine, launched in 2022, has once again pushed the international community to the edge of another catastrophic man-made nuclear incident. He pointed to repeated risks created by Russian military operations around the Chernobyl site, noting that Russian drones regularly fly over the decommissioned power plant, and one strike damaged the facility’s protective radiation containment shell in 2023. “The world must not allow this nuclear terrorism to continue, and the best way is to force Russia to stop its reckless attacks,” Zelensky added.
The anniversary commemoration coincided with one of the largest sustained drone barrages Ukraine has faced in months, part of the almost nightly Russian air attacks that have continued since the invasion began. Ukrainian officials confirmed that three people were killed and at least four more injured across the country in overnight strikes Saturday into Sunday. In the northeastern border region of Sumy, two civilian men aged 48 and 72 were killed in a drone strike on the Bilopillia community, located less than five kilometers from the Russian border, according to regional military administration head Oleg Gryborov. In the central-eastern city of Dnipro, a separate drone and artillery attack left one civilian dead and four wounded, damaging dozens of residential buildings and private vehicles, regional governor Oleksandr Ganzha confirmed.
Ukraine’s Air Force reported that Russia launched 144 drones in the overnight operation, and Ukrainian air defenses successfully intercepted and destroyed 124 of the incoming vehicles. The violence was not limited to Ukrainian-controlled territory: Mikhail Razvozhayev, the Moscow-appointed governor of Sevastopol in Russian-annexed Crimea, said a Ukrainian drone attack on the port city killed one man in his vehicle and damaged multiple residential buildings and a local dance school across several neighborhoods. Russian air defenses claimed to have shot down 43 drones in that attack. The latest wave of violence comes just one day after Ukrainian officials reported that eight civilians were killed in Dnipro during a 20-hour-long series of Russian strikes on the city Saturday.
