"It is clear that the militia has achieved a major success in intercepting Kyiv's military operation, which represents a grave danger to the population of Donbas and which has already led to the loss of many lives among civilians," the Russian leader said in a statement.
As a result of militias' counter-offensive, large number of Ukrainian troops - many of whom were taking part in Kyiv's so-called anti-terrorist operation "against their will" and "just following orders"- has been surrounded, the President added.
"I call on the militia groups to open a humanitarian corridor for Ukrainian servicemen who have been surrounded to avoid any senseless loss of life, giving them the opportunity to leave the combat area unimpeded and reunite with their families, to return them to their mothers, wives and children, and to quickly provide medical assistance to those who were injured in the course of the military operation," Putin said.
Russia in the meantime is ready and will provide aid to Ukraine's regions suffering from a humanitarian disaster, the Russian leader added.
"I once again call on the Ukrainian authorities to immediately stop military actions, cease fire, sit down at the negotiating table with Donbas representatives and resolve all the accumulated problems exclusively via peaceful means," Putin said according to the Kremlin's press service.
