Neutra was 21 when he was killed during the Oct. 7 attack and his body was taken into Gaza, where it remained for more than a year before being recovered under the current ceasefire.
His parents spoke of the long months when they believed he was still alive, describing how their lives had been shaped by waiting and uncertainty.
Senior Israeli and US officials also attended the ceremony, calling Neutra a figure tied closely to both countries.
For his family, the funeral marked the first time they had a place to grieve.
