Israel-Gaza live updates: IDF says it's discovered one of Hamas' biggest tunnels under Gaza

Israeli Minister of Health Uriel Buso and Director-General of the Ministry of Health Moshe Bar Siman Tov met Thursday with the president of the International Committee of the Red Cross to stress that the health of the hostages in Gaza is deteriorating by the day.

Israeli officials said they're calling for the ICRC to visit the hostages held by Hamas immediately to ensure they receive life-saving medical care.

"Hamas has already proven to the world that [it] does not hesitate to commit crimes against humanity, including against the elderly, women and children," Buso said. "We expect the president and the organization to do everything possible to end the suffering of the hostages and their families immediately."

There are 114 hostages believed to be alive or unaccounted for in Gaza, according to the Israeli prime minister’s office. Twenty-one hostages were believed to have been killed in captivity and their bodies remain in Gaza, the government said.

Raz Ben Ami was released from Hamas captivity two weeks ago, but her pain is far from over as her husband, Ohad, is still being held hostage.

"I’m not OK," she told ABC News in an exclusive interview.

"How can I be OK when he is there and I’m here?" she said. "We want our family back together."

Ben Ami and her husband were kidnapped separately from Kibbutz Be’eri. She said she tried to hide when she heard militants storming into her home and kidnapping her husband, but they found her and took her to Gaza on the back of a motorcycle.

She hasn’t shared the details of her time in captivity with her two daughters.

"She’s very afraid," said one of her daughters, Ella Ben Ami. "I can just imagine what Hamas did to her."

The mother and daughters said they will keep fighting for Ohad’s return by joining rallies and speaking to government officials.

"We’re here every night. That’s all we can do. What else can we do? Wait and hope," Raz Ben Ami said.

President Joe Biden said he wants Israel to "be more careful” with its attacks in Gaza and focus on "how to save civilian lives" as casualties continue to climb.

"I want them to be focused on how to save civilian lives. Not stop going after a Hamas, but be more careful," Biden said Thursday during an event at the National Institute of Health.

The president was asked if he wanted Israel to scale back its assault on Gaza by the end of the year and transition to a "lower intensity" phase, but he did not address the question.

Eleven people known to law enforcement as Hamas supporters were arrested for allegedly planning terrorist attacks in two separate investigations in Europe on Thursday, according to European law enforcement officials.

In one investigation -- which started before the Oct. 7 Hamas terrorist attack in Israel -- three people were detained in Berlin and one person was detained in the Netherlands under suspicion of planning terror attacks targeting Jewish institutions, Interpol officials told ABC News.

The three people detained in Berlin were allegedly trying to obtain heavy weapons since April, and law enforcement found a potential cache for hiding heavy weapons, officials said.

More arrests are expected, the officials added.
