Israel-Gaza updates: Gaza to run out of fuel Wednesday night, UNRWA says

The father of 23-year-old Hersh Goldberg-Polin, who was taken hostage by Hamas at the Supernova music festival, said he has gained some "strength" from seeing a video of his son on the day of the attack.

"No parent should ever be subjected to this sight," Jon Polin said on ABC News' "Good Morning America" on Tuesday.

Parents of Israeli American hostage speak out

Jon Polin and Rachel Goldberg open up about their son Hersh Goldberg-Polin, who was severely injured when Hamas attacked a music festival.

Polin and Rachel Goldberg's son was wounded in the Oct. 7 attack. He had been hiding with a group in a bomb shelter and witnesses saw him being loaded into the back of a Hamas pickup truck, his parents told ABC News earlier this month.

Goldberg-Polin's parents said on Tuesday they have since seen a video in which their son leaves the bomb shelter.

"Knowing he spent an hour to an hour and a half being subjected to this massacre and he then gets up with an arm freshly blown off and walks on his own two feet, under his own strength, towards this truck and uses his weak hand, his only hand now, to pull himself onto the truck while bloodied, but looking sort of composed," Polin said. "It gives me a sense of, he's got a perseverance and fortitude that we hope carries him through this."

Hospitals in Gaza are "horrific scenes," filled with killed and injured children and "medical staff working 24/7 with almost nothing in terms of resources and equipment," said Dr. Ashraf al-Qudra, a spokesman for the Health Ministry in Gaza.

Seventy-percent of the victims are children, women and the elderly, according to the health ministry.

The ministry said 12 hospitals and 32 health centers are out of service, with those numbers expected to rise as airstrikes continue and Gaza runs out of fuel.

"It's dire as it can be. The scenes inside the hospital are almost indescribable -- one of our doctors recently had to do an operation on the floor, in the corridor of the hospital, because there was nowhere to do it. The situation is untenable, absolutely horrific," al-Qudra said.

After Yocheved Lifschitz, 85, was taken hostage by Hamas militants, she was brought into a "huge network" of underground tunnels, which she described on Tuesday as being "like a spider's web."

"I've been through hell," Lifschitz told gathered reporters in the lobby of the Tel Aviv hospital where she's being treated. As Lifschitz spoke in Hebrew, her daughter translated her words into English.

The 85-year-old had been taken by motorcycle on Oct. 7, carried away through fields while her captors struck her with sticks and removed her watch and jewelry, she said. She was made to walk a few kilometers to the entrance of one of the many tunnels Hamas has built under Gaza.

Hamas frees 2 more hostages

The terrorist organization has now released four out of the over 200 hostages taken on Oct. 7 and one of the released hostages is now describing her ordeal saying she “went through hell.”

She said she was kept during her captivity in a "clean" location, where doctors visited every few days. Medicine was available, she said.

She slept on a mattress on one of the tunnel's floors. She ate white cheese, cucumbers and pita bread, she said.
