Putin stressed in the phone conversation that the Russian military is taking all possible measures to save the lives of civilians, and the main threat comes from Ukraine's nationalists, who "use the tactics of terrorists, hiding behind civilians," the statement said, Xinhua news agency reported.

Putin said that while Russian forces have declared a ceasefire several times to facilitate the evacuation of civilians along humanitarian corridors, Ukraine's nationalists used violence to prevent civilians from leaving, according to the statement.
