Holding back tears, Oleksandr Feldman, the park's owner, said later in a Facebook post that a 15-year old volunteer had been killed in the strike. He had been helping his parents to feed and get the animals evacuated.

Feldman said the teenager was the sixth member of the EcoPark's team to have been killed.
