Massive forest fires have engulfed more than 3,700 hectares (9,140 acres) of forest in Kharkiv Oblast, Ukraine's State Emergency Service said on June 1.
There were at least nine separate fires, most of which were started by Russian strikes, the State Emergency Service said. Six of the fires, encompassing around 2,300 hectares (5,680 acres) were contained.
The work of firefighters has been complicated by ongoing Russian attacks in the area and the presence of mines and other unexploded ordinance, the State Emergency Service said.
An investigation by NGL Media in April found that more than 60,000 hectares (148,000 acres) of forests have been destroyed since the beginning of Russia's full-scale war on Ukraine, amounting to at least Hr 14 billion ($360 million) in damages.
Ukraine's State Forest Resources Agency estimated in March that almost 30% of the country's forests have have suffered some kind of damage due to hostilities.
Environment Minister Ruslan Strilets told Deutsche Welle in January that the environmental costs of Russia's war have already exceeded Hr 2.2 trillion ($56.6 billion). Kyiv has recorded 3,600 Russian crimes against the environment, he added.
