Wagner, a Russian mercenary group leader, says the war in Ukraine will continue for years.
Russia does not discuss the timing of ending its military incursions into Ukraine, but private military contractors are eager for the war to continue as long as possible.
It is said that Russia used suicide drones on Friday, but it is unclear whether these drones are made by Iran or not.
Wagner, the owner of the Russian group, who is a private military contractor actively participating in the Ukrainian battles, has predicted that the war may last for years.
Yevgeny Prigozhin said in a video interview that the war in Ukraine may take 18 months to two years for Russia to fully control the industrial center of eastern Ukraine, namely Donbas.
He added that if Moscow decides to occupy larger areas east of the Dnieper River, the war could continue for three years.
