A Russian bomb struck two buses in the Ukrainian city of Kramatorsk Thursday, killing about 30 civilians and leaving debris and body parts strewn across the area.

As Russians step up their aggression in a series of deadly strikes in broad daylight, Ukrainians must remain on the alert around the clock. Another bomb struck a street in the city, adding 18 people to the death toll and bringing the number of those killed over this past week to 78, including children. A deliberate strike on a civilian bus would be classified as a war crime.

“Doctors are now fighting to save the lives of people injured in the Russian strike on Kramatorsk. As of now, 30 people have been confirmed killed, and sadly, that number may rise,” Ukrainian President Volodymyr Zelensky posted on X. “The Russian bomb effectively hit two city minibuses. Some of those killed have still not been identified because of the severity of their injuries. My condolences to all their families and loved ones. Another 18 people were injured in the strike. Residential buildings and cars were also damaged.”

“This strike will not go unanswered. Russia is trying to destroy all life in Donbas, and a response from the world is a must. A forceful response — exactly as the Russians deserve for all the deaths they have brought. May all those killed rest in peace,” he concluded.

Vadym Filashkin, regional governor of Kramatorsk, accused Russia of deliberately targeting civilians, forcing him to close down public transportation because of “the sharp deterioration of the security situation.”

Ukraine is struggling to defend itself amid a worldwide shortage of defense missiles driven by heavy use of the missiles during the Iran war. Zelensky has pleaded with the international community to send more military aid so Ukraine can deflect Russian ballistic missiles and drones.

Just yesterday, a series of devastating strikes on Kyiv and several regions across Ukraine, including Pryluky, Dnipro, Kremenchuk, and Oleksandriia, left about two dozen people dead, including five children.
