Israel-Gaza live updates: France, UK, Canada recognize Palestinian statehood

The Israel Defense Forces said in a post to X on Thursday morning that its forces are "expanding their activities in Gaza City" and continuing operations elsewhere in the Gaza Strip.

Divisions 162 and 98 are pressing Israel's assault on Gaza City -- the strip's largest urban area -- the IDF said in its post, destroying what it called "terrorist organization infrastructure" and eliminating "numerous" enemy fighters.

Meanwhile, the IDF's 143rd Division -- also known as the Gaza Division -- is operating in Khan Younis and Rafah in the southern Gaza Strip, the force said.

Qatar’s minister of state visited the International Criminal Court in the Hague “as part of the work of the team tasked with exploring legal avenues to respond,” to Israel’s strike on Doha, Qatar, earlier this month, the minister said in a post on X Wednesday.

“During the two meetings, I reaffirmed Qatar’s commitment to supporting the path of international justice and to ensuring accountability for perpetrators of crimes under international law—including wars crimes and acts of aggression —so as to prevent them from escaping punishment within the framework of international criminal law,” the minister said in the post.

The number of casualties in Gaza has already increased since Israel began its ground offensive on Gaza City, according to New York doctor and trauma specialist Dr. Michael Falk, who is providing care in Gaza for charity MedGlobal.

There have been "two mass casualty incidents" due to the IDF offensive in the last three days alone, Falk said. He has been based at Nasser Hospital in the southern Gaza city of Khan Younis for three weeks.

"If this ground offensive lasts months, it's going to be horrible," Falk said. "As soon as winter sets in you'll see more waterborne diseases, more respiratory illnesses, and people are already chronically malnourished. They can't heal. Post-operative wound infections are horrendous, and mortality is far higher than in the U.S."

Falk said there simply isn't enough room for the hundreds of thousands of Palestinians who fled Gaza City to live.

"There's literally no place for 350,000 refugees to go," he said.

"Mid-Gaza is a tent city from the Mediterranean to the eastern border. You can buy a tent for $400, rent the land, and then somehow feed your family -- but that's all while the war is going on around you," he added.

On Wednesday, he said he treated someone who had been "blown up" in an area of Gaza considered as the "green zone," whereas he says the area he works in is considered to be a more dangerous "yellow zone."

"One of my residents went home last night and his wife's entire family, aside from his father, were killed in the so-called safe zone. We had an ambulance driver shot outside the hospital this week. He died," he said.

"There really is no safe space in Gaza," he said.

Nasser Hospital is supposed to hold 300 patients. The hospital currently has more than a thousand, he said.

Falk has worked on multiple occasions in three conflict zones: Iraq in 2017, Ukraine after Russia's full-scale invasion in 2022 and in Gaza.

"Gaza is the worst I've ever seen," he said. "This feels indiscriminate. There is no reprieve, no calm place to go. It's constant and everywhere."

More than 400,000 Palestinians have evacuated Gaza City as Israel continues to expand its ground operation, according to the Israel Defense Forces (IDF). This leaves an estimated 600,000 people still in the city.

The IDF said 25 towers were destroyed in Gaza City on Tuesday after the expanded ground offensive began, Israel Defense Minister Israel Katz said in a post on X.

According to Katz, they were "terror towers" destroyed "in order to remove any threat of sniping from the maneuvering forces."

"If Hamas does not release the hostages and disarm, Gaza will be destroyed and become a monument to the atrocities and murderers of Hamas," Katz said.
