A 15-year-old teenager reportedly has been killed in eastern Ukraine while trying to help evacuate animals from a zoo. 

The Feldman Ecopark outside the city of Kharkiv – which has seen rampant fighting during the war – said Wednesday that "during the evacuation of buffaloes... the team of our employees and volunteers got under fire." 

"One person died. Two people were seriously injured. Doctors are fighting for their lives," it posted on Facebook
