Acute food insecurity is a concern across Gaza, but the issue is especially pressing in the northern part of the strip where the Israeli military's ongoing assault has intensified in recent weeks.

Dr. Abu Safiyeh -- who works at Kamal Adwan Hospital in Beit Lahiya -- said the besieged facility is running out of all food, collecting video footage of the deteriorating situation there.

Safiyeh's warning followed a statement last week from the United Nations' food assistance arm warning that "the ongoing humanitarian crisis in Gaza could soon escalate into a famine unless immediate action is taken."

The State Department said Monday that Israel has not done enough to improve humanitarian conditions in the Gaza Strip, as a 30-day deadline looms for Israeli officials to meet certain requirements or risk potential restrictions on military assistance.

The U.S. set out its conditions in a letter sent to Israeli officials last month and signed by Secretary of State Antony Blinken and Defense Secretary Lloyd Austin.

The letter gave Israel until Nov. 12 to increase the flow of humanitarian aid to the devastated Palestinian territory.

"As of today, the situation has not significantly turned around," State Department spokesperson Matthew Miller said.

"We have seen an increase in some measurements," Miller continued. "We've seen an increase in the number of crossings that are open. But just if you look at the stipulated recommendations in the letter, those have not been met."

Miller did not say what steps the U.S. would take if the situation did not improve before the deadline. "I don't want to forecast in any way what it is that we'll do at the end of those 30 days," he said.

Around 30 people were killed by Israeli strikes in the Gaza Strip on Monday, according to Palestinian health officials.

At least 20 people -- including eight women and six children -- were killed by an airstrike on a home sheltering several displaced families in the northern town of Beit Lahiya, officials said.

The town is at the heart of Israel's most recent offensive in the northern part of the strip, which officials at the Hamas-run Health Ministry say has killed around 1,800 people and injured another 4,000.

Separate strikes elsewhere in Gaza killed at least 10 people, health officials said.

More than 3,000 have been killed since the fighting between Israel and Hezbollah began over a year ago, according to the Lebanese Ministry of Public Health.

Sixteen people were killed in Lebanon on Sunday, bringing the death toll to 3,002, it said.
