Fighting has started again in eastern Ukraine between government troops and separatist rebels, Ukrainian military officials said.
Yesterday a missile killed at least 15 refugees who were trying to flee the area "burning them alive". More bodies may still be recovered.
This comes days after a convoy of aid supplies travelled to the country from Moscow but Ukraine is still to let them in over fears it could spark an invasion.
Refugees trapped in their vehicles after a missile hit the convoy they were travelling in were "burned alive," a Ukraine military spokesman has said.
"The force of the blow on the convoy was so strong that people were burned alive in the vehicles - they weren't able to get themselves out," military spokesman Anatoly Proshin told Ukrainian news channel 112.ua, Reuters reported.
Around 500 people a day have been fleeing Luhansk, a pro-Russian separatist stronghold that has been battered by months of fighting between rebels and Ukrainian forces and left almost entirely without water and electricity for more than two weeks.
