The WHO did not specify the number of casualties among ambulance workers, but said that since 2022 it has verified 1,682 attacks on healthcare facilities and workers in Ukraine that have resulted in 128 deaths and 288 injuries of health professionals and their patients.

Ukraine and Russia attacked targets on each other's territory on Thursday after brief direct talks between the two sides failed to make any progress on steps to end nearly three-and-a-half years of war.

Russia and Ukraine have traded aerial attacks overnight, resulting in two deaths in each country, with many wounded on both sides.
