At least 10,022 have died in Gaza since the Israel-Hamas conflict began on Oct. 7, the Hamas-run Gaza Health Ministry said Monday.

The death toll includes at least 4,104 children in Gaza, Ashraf Al-Qidreh, the ministry’s spokesperson, said during a press conference. The ministry's figures have not been independently verified.

The Israeli military on Monday accused Hamas militants of building "a whole tunnel system under" Sheikh Hamad Hospital in Gaza.

The practice of using hospitals as civilian shields has been "absolutely normal" for the militants, IDF spokesperson Jonathan Conricus said.

"Why it is this important? Because hospitals and other humanitarian facilities are supposed to enjoy special protections," Conricus said in a morning briefing. "But what Hamas is doing is that they've violating that special protection and using it for combat purposes."

More than 500 people have died in at least 102 strikes near or on health care facilities since Oct. 7, the World Health Organization said on Sunday.

"Over half of health attacks and over a half of hospitals damaged were in Gaza City," WHO officials said on social media. "Health care is #NotATarget."

During Monday's briefing, Conricus shared an IDF video that he said demonstrated there were Hamas tunnels under the hospital. He also shared several photos that he said dated back to at least 2010, when the hospital was being constructed. The groundwork for the Hamas tunnels was put in place at that time, he said. ABC News was not immediately able to verify the claims.

In a photo said to be from 2023, rocket-launching sites could be seen along the outskirts of the facility, Conricus said. He presented another photo of what he said was the opening of a Hamas tunnel on the grounds.

"We know that underneath this entire complex, there's an entire Hamas infrastructure underground," Conricus said. "And it is absolutely normal. This is how Hamas operates all around the Gaza Strip."

Israeli forces took control of a Hamas compound in the Gaza Strip, as the military continued its bombardment of the enclave overnight, the Israel Defense Forces said Monday.

The Hamas compound included a web of "underground terror tunnels," as well as training areas and observation posts, the military said in a post on Telegram. Israel did not disclose the location of the compound. ABC News was not immediately able to verify IDF's claims.

"During the operation, several Hamas terrorists were killed," Israel said.

Israeli munitions struck "in the last day" at least 450 other sites throughout Gaza, "including tunnels, terrorists, military compounds, observation posts, anti-tank missile launch posts and more," IDF officials said.

"Moreover, IDF naval soldiers struck command centers, anti-tank launch posts and additional observation posts belonging to the Hamas terrorist organization," IDF officials said in the post.

King Abdullah II of Jordan says his country dropped aid by parachute into northern Gaza at midnight.

"Our fearless air force personnel air-dropped at midnight urgent medical aid to the Jordanian field hospital in Gaza," read a post on X (formerly Twitter). "This is our duty to aid our brothers and sisters injured in the war on Gaza. We will always be there for our Palestinian brethren."

The king posted two photos of a crate with the flag of Jordan on it being loaded onto an airplane.

Through tears and voices choked with raw emotion, people whose family members are believed to held hostage by Hamas pleaded for help during a Republican-led press conference at the U.S. Capitol on Tuesday.

Doris Liber told reporters that her son, Guy Iluz, called her as Hamas unleashed its terrorist attack against Israel on Oct. 7 and she hasn't heard from him since.

"I'm here because it's been 30 days. Every day is like eternity to me," Liber, who holds joint Israeli-American citizenship, said. "We don't have a list of the hostages. We don't know their condition. I don't have anything. So I need your help."

She described the last time she spoke to her son.

"We hear shots in the background," she said. "He was shot in the arm and he wasn't able to stop the bleeding and he was trying to say his last words."

“I tried to, you know, tell him, ‘Guy I love you. Don't worry, nothing's going to happen. I'm going to end the call now. I'm going to send somebody now to get you,'" she continued. "And that's what I did. I hung up and I regret that since I didn't hear from him since."

Yonatan Lulu-Shamriz said he was awoken by his pregnant wife as the sirens began to sound in their kibbutz. They grabbed their 3-year-old daughter, huddled in a safe room and listened as their neighbors were slaughtered, he said. Soon his brother, Alon, called to report he was under attack, Lulu-Shamriz said.

“We don't know what is their condition," Lulu-Shamriz said. "This is a wake-up call not only for Israel, not only for the Jewish community. This is a wake-up call for all of you -- all of you here, all of America, all of Europe. You are next. You are next. And we should do everything that we can to stop these atrocities."

House Speaker Mike Johnson vowed to "take action."

"We're resolved to help," the newly minted speaker said. "House Republicans want to do that."
