This was reported by the legitimate mayor of Mariupol, Vadym Boychenko.
"The occupiers were taken to the city hospital No. 2. 13 of them have already died," he said.
"In Manhush settlement, the hospital is full, as for the dead, we know about 5 occupiers. All night long we were cleaning up the aftermath and taking out the wounded, corpses and removing damaged equipment," the mayor added.
Judging by the number of buses and trucks marked "300," (with injured soldiers) the number of wounded is high, Boychenko noted.
In addition, military equipment was burned.
According to the mayor, there were no civilian casualties.
On August 14, the Ukrainian Armed Forces attacked the occupiers' command post near Mariupol.
