Volunteer EMT Kalanit Taub, a first responder at the scene, told CNN there was “non-stop people to care for" in the wake of the crush.
Taub described place where the crush occurred as a "horrific scene," and said that there were people giving CPR everywhere she looked.
“Literally, I saw twenty-plus CPRs ongoing at the same time,” Taub said.
“Anywhere you looked, you saw another person doing CPR … it was just nonstop one after another.”
She added that a paramedic next to her was declaring person after person dead.
Taub, who is also a member of a psychological trauma treatment unit, said she also took care of nearly 100 people in the aftermath of Friday’s incident in addition to performing CPR.
“I was walking around the site for a number of hours afterwards and there were people on the side crying or just staring into space and I helped them process what they were dealing with," she said.
“They didn’t know how to cope with what they had just seen,” she said.
Taub recalled how the religious gathering went from a joyous occasion to a disaster very quickly.
“In seconds it went from a site where people were singing and joyous, to mass chaos, pandemonium and death,” she said.
