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.

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.

The Israel Defense Forces said Tuesday morning that three Hamas deputy commanders were killed Monday night.

“During the night, IDF aircraft also attacked operational headquarters used by operatives of the terrorist organization Hamas and assembly points of the terrorist organization located inside mosques,” the IDF said in a post on X (formerly Twitter).

The deputy commander of the Nusirat battalion, the deputy commander of the Shati battalion and the deputy commander of the Alfurkan battalion of Hamas were killed, the IDF said in the post.

President Joe Biden spoke with Israel’s Prime Minister Benjamin Netanyahu on Monday afternoon, once again addressing his commitment to efforts to “secure the release of all remaining hostages taken by Hamas – including Americans – and to provide for safe passage for U.S. citizens and other civilians in Gaza,” according to a White House readout of the call. Biden welcomed the news of the two hostages who were released earlier on Monday, per the readout.

During the call, Biden also “underscored the need to sustain a continuous flow of urgently needed humanitarian assistance into Gaza,” according to the readout.

Biden also spoke with Netanyahu about U.S. support for Israel and what the White House said was “ongoing efforts at regional deterrence, to include new U.S. military deployments.”

White House National Security Council spokesman John Kirby said Monday that in recent days there had been "an uptick in rocket and drone attacks by Iranian-backed proxy groups against military bases housing U.S. personnel in Iraq and Syria."

“We know Iran continues to support Hamas and Hezbollah, and we know Iran is closely monitoring these events and in some cases, actively facilitating attacks and spurring on others who may want to exploit for their own good, or for that of Iran," Kirby said.

Kirby said Iran tries to "maintain some level of deniability here, but we’re not going to allow them to do that."

He added that there is still no direct evidence that Iran was involved in Hamas' Oct. 7 terrorist attack on Israel.

Israeli Foreign Minister Eli Cohen and the Palestinian Authority’s Minister of Foreign Affairs Riyad al-Maliki, gave long, impassioned speeches at the United Nations Security Council meeting about the suffering their people are experiencing.

Cohen began by holding up photographs of the Israeli children kidnapped by Hamas, reading out their names and ages.

"They are just a few the many children and babies that have not seen evil. They have not caused evil. But they are victims of evil," he said.

Cohen described Hamas as "the new Nazis" and said Hamas' Oct. 7 attack on Israel should serve as "a wakeup call against extremism."

Al-Maliki purported that Israel’s retaliation had equated to "ongoing massacres being deliberately, systematically, and savagely" perpetrated against Palestinians civilians.

"The Security Council has a duty to stop them," he said. "It is our collective human duty to stop them now."

He suggested that Israel's campaign would ultimately lead to more conflict, saying "more injustice and more killing will not make Israel safer."

The foreign minister argued that everyone on the council should be united behind one goal.

"We should be on the same side -- all of us who believe in justice and peace," he said. "We should stand shoulder to shoulder in these moments. But that is only possible if everyone recognizes the value of Palestinian life -- the need to uphold Palestinian rights."
