'We have no water': Gaza faces deeper humanitarian crisis as Israel tightens its hold

A humanitarian crisis is swiftly unfolding in Gaza, as trapped residents, many cut off from food and electricity, face a fourth day of Israeli airstrikes in response to Hamas' deadly attack on Israel, during which it has killed at least 1,000 people and taken up to 150 hostages.

Nadine Abdul Latif, 13, of Gaza City's Al Rimal neighborhood, said she and her family were told by neighbors and relatives to leave on Monday after Israel said it would target the area. But they decided to stay as "we have no safe place to go to," she said.

Her father Nihad has been missing since Saturday. He had been working in Israel, but after Hamas' Saturday attack, the family lost touch with him.

The Gaza strip - the coastal enclave that Hamas controls - has been pummeled by airstrikes since Israeli Defense Minister Yoav Gallant ordered a "complete siege" on the area, including halting supplies of electricity, food, water and fuel to the enclave. "We are fighting barbarians and will respond accordingly," Gallant said.

Israeli fighter jets struck more than 200 targets in Gaza overnight, the Israel Defense Forces said in a statement. The death toll in Gaza now stands at over 900 people according to the Palestinian Ministry of Health in Gaza.

The Palestinian interior ministry said most of the targets were "towers, residential buildings, civil and service facilities, and many mosques." Hamas denied that it used any of the targeted towers.

Tariq Al Hillu, a 29-year-old resident of Al Sudaniya in northern Gaza, described complete chaos when airstrikes struck his neighborhood Sunday morning.
