"They [battalion], began firing at civilians who left this village, as well as at anything that moves… One local resident was wounded in his leg, but luckily he lost little blood," journalist Artyom Kol told Russian TV channel Rossiya-24.
Kiev-led troops and independence fighters in eastern Ukraine have traded blame for fatal shelling incidents in the region in recent weeks. The attacks killed dozens and wounded hundreds of civilians in conflict-torn cities of Donetsk, Mariupol and Debaltseve, a key rail junction, which has been a hot spot of violence.
Prior to the latest agreement, violations of the September, 2014 Minsk ceasefire deal have continued unabated since the start of 2015, which saw intensified fighting between independence supporters and Kiev forces that launched a military operation in Ukraine's southeast in mid-April last year.
