Yaacov Argamani was inconsolable as he watched Noa, 25, being forced on to the back of a motorcycle by militants.
Noa is heard screaming, “Don’t kill me! No, no, no!” as she stretches out her arms to boyfriend Avi Nathan, who was led away at gunpoint.
Noa was driven down a dirt track. Last night, the fate of the couple remained unknown.
Mr Argamani said: “I was always so protective, but in this moment I couldn’t protect her.
“All my life since she was born, I have tried to protect and hug her, support and love her.”
It comes amid reports of “a massacre” at an all-night celebration attended by hundreds, at the end of the Sukkot religious holiday.
As dawn broke, armed Palestinian militants opened fire on revellers after swooping down on paragliders near Kibbutz Urim, close to the Gaza border. Footage later emerged of an unconscious half-naked woman who had attended the event, paraded in a truck through Gaza’s streets, as passers-by spat at her.
The victim was later named as German tourist Shani Louk, 30.
Festivalgoer Gili Yoskovich recalled: “I saw people dying all around. I was very quiet, lying there for three hours.”
Meanwhile, video footage captured terrified Israeli householders hiding from gunmen – among them Adva Adar’s grandmother Yaffa, 85, who was taken after her house in Kibbutz Nahal Oz was torched. Ms Adar said: “I was on the phone with her and heard men shouting in Arabic outside, then we lost touch.
“She is 85 and sick and has no medicine with her, we don’t know where she is or if she has food or water or even if she survived.”
“The video they proudly posted shows her entering Gaza and the people screaming at her. This is our worst nightmare.”
