The National Security and Defense Council of Ukraine released a statement indicating 13 civilians, 18 pro-Russian separatists, and four Ukrainian soldiers had died in the fighting.
The statement added that at least 42 attacks had been carried out in the towns of Debaltseve, Troitskoe, Redkodub, Sanzharovka, Chernukhina, Zolotoe and Novogrigorovka in eastern Ukraine by separatists in the past 24 hours.
Twenty-five Ukrainian soldiers were wounded as were 55 pro-Russian separatists in the clashes, according the Ukrainian Defense Council.
Separately, nine people were killed and five others were wounded by stray bullets fired from heavy weapons in two different pro-Russian rebel hospitals in Donetsk. Separatists blamed the Ukrainian army for the attacks.
Furthermore, the Ukraine Chief Public Prosecutor's office released a statement confirming another separatist attack on Donetsk's Kirovsky district.
Four to 10 people were killed in what the statement described as "a terrorist attack" by pro-Russian rebels.
According to the UN high commissioner for human rights, more than 5,300 people have been killed and 12,200 others injured in eastern Ukraine since mid-April last year in the ongoing conflict between the Ukrainian army and pro-Russian separatists.
