Ukrainian officials said this week that roughly a third of all its infrastructure had been demolished by Russia’s invading forces as the war continues for the 54th day.

Infrastructure Minister Oleksander Kubrakov said that $100 billion in damage had been inflicted on the nation’s infrastructure but added that the bill could run as high as $500 billion when everything from homes to roads had been tallied up, first reported Reuters.

“Practically all components of our transport infrastructure have suffered in one form or another,” Kubrakov told the publication Monday. “If we talk about roads, bridges and residential buildings, I believe that almost everything can be rebuilt in two years.

“If everyone works quickly,” he added.
