City hall in Luhansk, which is under the control of separatist rebels, said today that five people were killed when an old people's home was struck by artillery fire. Russian television showed images of bodies in wheelchairs covered with blankets.
In Horlivka, a city besieged by government troops, the mayor's office reported 17 people, including three children, dying as a result of shelling.
The use of unguided rockets in fighting between government forces and pro-Russian separatist rebels has been taking a noticeably heavier toll in recent weeks and been criticised by rights groups.
