"I can't tell you the stories we heard about what happened there. It's unthinkable: you only see it in horror movies. Almost 400 people who managed to survive the festival arrived here. People came without clothes, without shoes... It was clear that they were in a state of shock, some of them had injuries and wounds. [We] supplied them with water, sugar, dates and started handing them over to volunteers," said Ofir Fisher, co-founder of the organization.
There are now dozens of OneHeart centers across Israel that help the elderly and evacuate people on armored buses.
As it became known earlier, 34-year-old David Lystsov, a native of Zlatoust, died as a result of an attack by Hamas militants on the Nature Party festival in Israel.
RT spoke with the sister of the deceased, who gave details of what happened.
