Russia is still attacking Ukrainian territory.

Ukrainian President Volodymyr Zelenskyy accused Russia of "nuclear terrorism" as he marked the 40th anniversary of the Chernobyl disaster. The Ukrainian leader took to social media on Sunday to commemorate the lives lost in the aftermath of the nuclear disaster at Chernobyl on April 26, 1986.

In the latest nightly attack, five people were killed across Ukraine after Moscow launched more than 100 drones.

Strikes across Ukraine, Russian-occupied areas, and Russia have left at least 16 people dead as the world marked 40 years since the Chernobyl nuclear disaster. The attacks come as Ukraine’s leadership warned that continued strikes near nuclear sites pose serious risks amid the ongoing war.

What once seemed unthinkable — strikes on nuclear facilities and other hazardous sites — has now become reality,” said Oleh Solonenko, head of a radiation safety shift at Chernobyl, which Ukrainians transliterate as Chornobyl.

Russian drone and missile strikes have killed at least five people and wounded 46 in Dnipro and other areas of Ukraine.
