Israel's ongoing war on Palestinians raised fear of a broader conflict after Israeli warplanes hit multiple targets across Gaza, two airports in Syria and a mosque in the occupied West Bank on Sunday.
It has also traded fire with Lebanon's Hezbollah group on a near-daily basis since the war began, and tensions are soaring in the Israeli-occupied West Bank, where Israeli forces have carried out raids and attacks on refugee camps and carried out two airstrikes in recent days.
For days, Israel has seemed to be on the verge of launching a ground offensive in Gaza as part of its response to Hamas' Oct. 7 incursion. Tanks and tens of thousands of troops have massed at the border, and Israeli leaders have spoken of an undefined next stage in operations.
But the there are still hundreds of thousands of Palestinian civilians in northern Gaza, with nowhere to go, despite a sweeping evacuation order, which would complicate any ground attack. And the risk of triggering a broader war in Lebanon and Syria might also give them pause.
On Saturday, 20 trucks of aid were allowed to enter Gaza from Egypt through the Rafah crossing, the first time anything has gone into the territory since Israel imposed a complete siege two weeks ago.
Aid workers said it was far too little to address the spiraling humanitarian crisis in Gaza, where half the territory's 2.3 million people have fled their homes. Hospitals packed with patients and displaced people are running low on medical supplies and fuel for generators, forcing doctors to perform surgeries with sewing needles, using kitchen vinegar as disinfectant, and without anesthesia.
Shortages in supplies, including ventilators, are forcing doctors to ration treatment, said Dr. Mohammed Qandeel, who works in Khan Younis' Nasser Hospital.
"It's heartbreaking," he told The Associated Press (AP). "Everyday, if we receive 10 severely injured patients we have to manage with maybe three or five ICU beds available."
Palestinians sheltering in U.N.-run schools and tent camps are running low on food and drinking dirty water. The territory's sole power plant shut down over a week ago, causing a territory-wide blackout and crippling water and sanitation systems.
The U.N. humanitarian agency said cases of chicken pox, scabies and diarrhea are on the rise because of the lack of clean water.
Gaza's Interior Ministry reported heavy Israeli airstrikes across the territory overnight into Sunday, including southern areas where Israel had told Palestinians to seek refuge.
Late Saturday, an airstrike hit a cafe in the southern town of Khan Younis where displaced people had gathered to charge their phones. The nearby Nasser Hospital said 12 people were killed and 75 wounded.
Israeli Prime Minister Benjamin Netanyahu convened his Cabinet late Saturday to discuss the expected ground invasion, Israeli media reported. A military spokesman, Rear Adm. Daniel Hagari, said Israel planned to step up airstrikes starting Saturday as preparation for the "next stages of the war."
An Israeli ground assault would likely lead to a dramatic escalation in casualties on both sides. More than 4,300 people have been killed in Gaza, according to the Health Ministry. That includes the toll from a hospital explosion. In comparison, the Israeli death toll is near 1,400.
Syrian state media meanwhile reported that Israeli airstrikes have targeted the international airports in the capital, Damascus, and the northern city of Aleppo. It said the strikes killed one person and damaged the runways, putting them out of service.
Israel has carried out several strikes in Syria, including on the airports, since the war began. Israel rarely acknowledges individual strikes.
In Lebanon, Hezbollah said six of its members were killed Saturday, and the group's deputy leader, Sheikh Naim Kassem, warned that Israel would pay a high price if it starts a ground offensive in the Gaza Strip. Israel struck Hezbollah targets early Sunday in response to rocket fire, the military said.
Israel also announced evacuation plans for another 14 communities near the border with Lebanon. Kiryat Shmona, with a population of more than 20,000 people, was told to evacuate last week.
In the occupied West Bank, dozens of Palestinians have been killed by Israeli troops and Jewish settlers. Israeli occupying forces have closed crossings into the territory and checkpoints between cities.
Israel also said it has arrested more than 700 Palestinians since Oct. 7, including 480 suspected Hamas members.
The internationally recognized Palestinian Authority administers parts of the West Bank and cooperates with Israel on security, but it is deeply unpopular and has been the target of violent Palestinian protests.
Israeli forces killed at least five people early Sunday in the West Bank, according to the Palestinian Health Ministry. Two were killed in an airstrike on a mosque in the town of Jenin.
The Israeli military alleged the mosque compound belonged to Hamas and Islamic Jihad members who had carried out several attacks in recent months and were planning another one.
Sunday's fatalities brought the death toll in the West Bank to 90 Palestinians since the war broke out on Oct. 7, according to the Health Ministry. Most appear have been killed during fighting with Israeli forces or violent protests.
Thirteen Palestinians, including five minors, and a member of Israel's paramilitary Border Police were killed last week in a battle in a refugee camp in the West Bank town of Tulkarem, in which Israel also launched an airstrike.
In Gaza, the Israeli military said the humanitarian situation was "under control" as aid workers called for the opening of a round-the-clock aid corridor.
The U.N. humanitarian agency, known as OCHA, said the convoy that entered Saturday carried about 4% of an average day's imports before the war and "a fraction of what is needed after 13 days of complete siege."
It is calling for 100 trucks a day to enter. Huge quantities of aid have been gathered near the Egyptian side of the crossing, but there has been no word on when more might enter.
No fuel has entered Gaza, even as hospitals are struggling to keep vital medical equipment running with generators. Dozens of patients continue to arrive each day, many with blast injuries from airstrikes.
Most treatment is carried out in crowded, darkened corridors, as hospitals preserve electricity for intensive care units and incubators for newborns.
Nasser Hospital managed to secure some fuel from the U.N. agency for Palestinian refugees Saturday, enough for three to five days, Qandeel said.
