Israel-Gaza updates: Israel says ground operation underway in southern Gaza

Thursday morning's shooting carried out by Hamas at a Jerusalem bus stop did not violate the cease-fire agreement because "this attack happened in Jerusalem" and "the pause is in the fighting more specific to Gaza," National Security Council spokesperson John Kirby said.

"It didn't technically violate the deal that was in place, but obviously it's a stark reminder of who they’re facing and what kind of enemy they’re opposing," Kirby continued.

"If anybody's guessing and wondering whether Hamas still has murderous intentions against the Israeli people, just look at what happened in Jerusalem," Kirby said.

At least three people were killed in Thursday's shooting. The two gunmen were killed by two off-duty Israeli soldiers and a civilian who were near the scene, according to Israeli police.

Hamas claimed responsibility, saying the shooting was in response to Israel's "unprecedented crimes" including "brutal massacres" in Gaza and the killing of children in the occupied West Bank.

About 80% of Gaza’s population is now homeless, with many people forced to live in make-shift shelters, largely exposed to the elements, according to the United Nations.

The bad weather is compounding an already difficult situation, several Gaza residents told ABC News in interviews conducted during the last two weeks. People living in tents are struggling to make them watertight. They are patching them up as best they can with tarpaulin. The rainy season in Gaza usually begins in late November or early December and temperatures can get as low as 50 degrees Fahrenheit.

"At 6 in the morning, we woke up to rain falling and the place was soaked with water," Iqbal Saleh Mohsen Abu Al-Saud, one resident, told ABC News, when the winter rains first came to Gaza last week.

"We are 30 people in this tent,“ he explained. "We were displaced from Gaza City from the Sheikh Radwan neighborhood. We went from home to schools, then to tents, from place to place. Without food or shelter, we only left our homes because of the bombing."

Two Israeli hostages released in the Gaza Strip -- 21-year-old Mia Schem and 40-year-old Amit Sosna -- have been transferred to the Red Cross and are now on their way to Israel, the Israel Defense Forces said Thursday evening.

More hostages are expected to be released in the coming hours, according to the IDF.

The World Health Organization said Thursday that it has documented 427 attacks on health care in the Gaza Strip and the West Bank since Oct. 7.

Those attacks have resulted in 566 fatalities and 758 injuries, according to the WHO.

“Health care and civilians must be actively protected,” the WHO wrote in a post on X, the social media platform formerly known as Twitter.
