Palestinians say heavy fighting is underway in northern Gaza, where Israel has ordered another wholesale evacuation and launched a ground operation a year into the war with Hamas.

At least 15 people, including two women and four children, were killed Tuesday in the fighting in Jabaliya, the nearby Kamal Adwan Hospital said.

The Biden administration has in recent weeks grown “increasingly distrustful” of what the Israeli government says about its military and diplomatic plans in the multi-front war it is fighting, four U.S. officials told U.S. news portal Axios.

Israeli Prime Minister Benjamin Netanyahu said Monday that Israel was fighting a “war of resurrection” and would continue until achieving its goals, as Israelis marked the anniversary of the Hamas attack.

“This is the war of our existence — the ‘war of resurrection’. This is what I would like to officially call the war,” Netanyahu said during a Cabinet meeting.

The war in Gaza was always personal for many Palestinian refugees in Lebanon.

Israel launched a new air and ground offensive in northern Gaza Sunday, hours after pounding Beirut's southern suburbs in the heaviest bombardment since it stepped up its pursuit of Hezbollah last month.

The intensified campaign on two fronts, including an overnight strike on a Gaza mosque that killed 19, came as Israel remained on high alert ahead of memorial events to mark the surprise attack a year ago that triggered the ongoing war.

President Joe Biden said Monday, on the anniversary of the Hamas attacks, that the United States remains "fully committed" to Israel's security, and that Israel has the right to defend itself against Hamas, Iran and others.

"One year later, Vice President (Kamala) Harris and I remain fully committed to the safety of the Jewish people, the security of Israel, and its right to exist," Biden said in a statement marking the first anniversary of the October 7 attacks by Hamas.

Crowds were participating in pro-Palestinian and pro-Israeli protests and memorial events across Europe, North Africa and Asia on Sunday on the eve of the first anniversary of the Hamas attack on Israel.

Sunday's events followed massive rallies that took place Saturday in several European cities, including London, Berlin, Paris and Rome. Other events are scheduled through the week, with an expected peak on Monday, the date of the anniversary.

Thousands of people have demonstrated in the streets of Morocco’s capital to call for justice for the Palestinians and for the Moroccan government to revoke its 2020 agreement formalizing its ties with Israel.

The North African nation has had — since the Oct. 7 attack on Israel by Hamas — some of the Arab world’s largest protests.

President Emmanuel Macron’s office said the French leader has had a “frank” discussion about the Middle East situation with Israeli Prime Minister Benjamin Netanyahu.

Both leaders accepted their divergence of views, as well as their desire to be well understood by each other, Macron's office said in a statement.

The United States has spent a record of at least $17.9 billion on military aid to Israel since the war in Gaza began and led to escalating conflict around the Middle East, according to a report for Brown University's Costs of War project, released on the anniversary of Hamas' attacks on Israel.

An additional $4.86 billion has gone into stepped-up U.S. military operations in the region since the Oct. 7, 2023, attacks, researchers said in findings first provided to The Associated Press. That includes the costs of a Navy-led campaign to quell strikes on commercial shipping by Yemen's Houthis, who are carrying them out in solidarity with the fellow Iranian-backed group Hamas.
