US aircraft carrier strike group arrives in Middle East

At least 46 people have been killed in Gaza in the last 24 hours according to the Gaza Ministry of Health in the Hamas-run territory.

The expulsion of residents from the northern part of the strip continues amid Israel's intense offensive operation there, the Gaza Civil Defense reported.

The body said people sheltering at a school in Beit Hanoun -- on the northeastern tip of Gaza close to areas of intense fighting like Beit Lahia and Jabalia -- were forced to leave on Sunday morning, with young men arrested.

The Israel Defense Forces said in a statement that its troops "conducted a targeted raid on a terrorist meeting point in the Beit Hanoun area."

In coordination with warplanes, "the troops struck dozens of terrorists from both the air and ground and additional terrorists were apprehended," the IDF said.

Escalating clashes between Palestinian Authority security forces and militants in the West Bank city of Jenin overnight left multiple civilians injured and at least one fighter killed, according to four local sources.

PA forces are seeking to "eradicate sedition and chaos" according to local media citing a PA spokesperson. But Jenin residents and local journalists reported unarmed crowds being targeted by tear gas and gunfire amid protests over the security forces actions.

Locals told ABC News that the PA operation -- which is coordinated with Israel -- has been ongoing for five days, besieging a refugee camp in the city.

The Syrian Observatory for Human Rights monitoring group reported 75 Israeli airstrikes across Syria overnight Saturday into Sunday, bringing its total tally since the fall of former president Bashar Assad to around 453.

The renewed strikes come despite an appeal by Ahmed al-Sharaa -- the leader of victorious rebel group Hayat Tahrir al-Sham, who is also known by his "nom de guerre" Abu Mohammed al-Jolani -- for calm.

Sharaa said HTS and the Syrian transitional government have no interest in being dragged into a new conflict, calling on the international community to pressure Israel to stop its attacks inside Syria. Israel's justification for its strikes, Sharaa said, are now "weak."

At least seven people, including a child, were killed and 30 others were injured in an Israeli strike on the Al-Majda Al Wasilah School complex in Gaza City.

The Israel Defense Forces said it was targeting Hamas militants in the school.

Later in the day 11 people were killed in a strike on the Deir al-Balah municipality building, in the "humanitarian area," which has been targeted previously. The death toll is according to the Gaza Civil Defense.

The mayor of Deir al-Balah, Dr. Diab Al-Jarou, was killed in the strike, according to the Hamas Government Media Office. He is the fourth central Gaza mayor to be killed in Israeli strikes, after the mayors of Al Zahra, Al Maghazi, and Nuseirat, according to the government media office.

The IDF claims the mayor was simultaneously a member of Hamas' military wing and that the strike was targeting him.

At least 55 people were killed in the last 24 hours, bringing the total number of people killed in the war to 44,930, according to the Gaza Ministry of Health.
