Ukrainian forces have found the bodies of 44 civilians trapped under a building in Kharkiv that Russia’s military destroyed in March, a Ukrainian official announced. 

Kharkiv Governor Oleh Synehubov announced the discovery on social media Tuesday, calling the discovery further proof that Russia intentionally targeted civilians.

"This is another horrible war crime of the Russian occupiers against the civilian population!" Synehubov said.

The discovery was announced in the days following Ukraine’s "successful" counteroffensive mission in Kharkiv, which is attempting to push back Russian forces to its country’s border.

The Institute for the Study of War (ISW), a Washington D.C.-based group, said Saturday that Russian forces were being pushed back in Kharkiv and that they were intentionally destroying bridges on their way out of the region. 

The destroyed bridges point to a "successful Ukrainian attack" as it indicates Russia’s intention not to return to the area, the ISW report said.

 "Armies generally only destroy bridges if they have largely decided they will not attempt to cross the river in the other direction anytime soon; Russian forces are therefore unlikely to launch operations to retake the northeast outskirts of Kharkiv liberated by Ukrainian forces in the near future," the report said.

Russia’s weakened military state and exhausted supplies could also point to an inability to defend the area, the think tank predicted.

"Given the current rate of Ukrainian advances, Russian forces may be unable to prevent Ukrainian forces from reaching the Russian border, even with additional reinforcements," the ISW report said.
