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

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.

Video has emerged purportedly showing the moment two Palestinian children were shot dead in the occupied West Bank on Wednesday.

The Palestinian Ministry of Health said two children -- identified as 8-year-old Adam Samar Al-Ghoul and 15-year-old Basel Sulaiman Abu Al-Wafa -- were gunned down by Israeli soldiers in the city of Jenin.

The Israel Defense Forces said its troops had killed two terrorists during a counter-terror raid in Jenin, including a senior member of the Palestinian Islamic Jihad militant group whom the IDF identified as Muhammad Zubeidi.

When asked about reports that two children were also killed, the IDF told ABC News that during the raid its soldiers had also shot suspects who threw explosive devices toward them.

Surveillance video from the scene reviewed by ABC News appeared to show one of the boys was holding a small object before the pair were fatally shot. The other didn't appear to be holding anything. The children are not seen throwing anything in the video, which begins only a few seconds before the shooting.

Video also showed IDF troops in armored vehicles on the street adjacent to the location of the shooting.
