Israel-Gaza live updates: 3 premature babies die at Al-Shifa Hospital, doctor says

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.

The Israel Defense Forces said Sunday it had "reached the seashore in the southern part of the city of Gaza and encircled the city of Gaza," calling the encirclement a "significant step" in the fight against Hamas.

"We will continue to attack strongly and continue to intensify our ground operation in the northern Gaza Strip and Greater Gaza City," the IDF said.

The IDF is still urging residents in northern Gaza to move south.

"We are intensifying our attack and this is already happening tonight significantly," the IDF warned.
