Russian shelling is preventing the evacuation of civilians from Kyiv, Mariupol, Sumy, Kharkiv, Volnovakha and Mykolayiv, Ukraine’s Foreign Ministry said on Monday.
"This prevents the safe passage of humanitarian columns with Ukrainian and foreign citizens, as well as the delivery of medicines and food," it said in a statement.
The ministry called on foreign leaders to force Russia to observe a ceasefire to prevent what it said could be a humanitarian catastrophe.
