LIVE UPDATES: Israeli Fighter Jets Strike HQ of Hamas– IDF

At least 37 Palestinians have been killed in the Israeli shelling of the city of Jabaliya in the northern Gaza Strip, media reported Wednesday, citing the Palestinian Interior Ministry.

Israeli National Security Minister Itamar Ben-Gvir said Tuesday that, until Palestinian movement Hamas releases hostages, the only thing that should be sent to the Gaza Strip is "hundreds of tonnes of explosives" but not humanitarian aid.

The Israel Defense Forces said Wednesday that its soldiers came under fire in the area of Israel's northern town of Shtula and the area of the security fence between Israel and Lebanon.

Opportunities to treat wounded in the Gaza Strip will run out in several hours, Palestinian Health Ministry spokesman Ashraf Al Qudra said Wednesday.

"The flow of casualties has exceeded the capacity of medical teams and ambulances ... In several hours, we will announce the exhaustion of remaining options for treatment," Al Qudra told a news conference.

Iranian President Ebrahim Raisi on Tuesday called the strike on a hospital in the Gaza Strip a war crime and said that the "flames of US-Israeli bombs will soon engulf" Israel.

UN Secretary-General Antonio Guterres condemned a strike on a Gaza hospital that killed hundreds of Palestinian civilians.

"I am horrified by the killing of hundreds of Palestinian civilians in a strike on a hospital in Gaza today, which I strongly condemn. My heart is with the families of the victims. Hospitals and medical personnel are protected under international humanitarian law," Guterres said in a social media post on Tuesday.

The Arab group of the United Nations calls for an immediate end to the conflict in Gaza in the wake of the hospital strike that killed 500, a situation the Security Council could have prevented, Palestinian Ambassador to the UN Riyad Mansour told reporters while standing alongside Arab counterparts.

On Monday, the UNSC rejected a Russian-proposed draft resolution to resolve the humanitarian crisis in the Gaza Strip.

"We as an Arab group, demand immediately a ceasefire because the continuation of the war... means killing more Palestinians every moment," Mansour said on Tuesday. "Had the Security Council showed that it's responsible, civil responsibility, yesterday... then we would have been able to have those 500 killed still alive and with us. So the Security Council has to wake up."

US President Joe Biden is postponing his trip to Jordan on Wednesday where he was initially scheduled to meet with his counterparts from Egypt, Palestine, and Jordan, a White House official said in a statement.

"After consulting with King Abdullah II of Jordan and in light of the days of mourning announced by President Abbas of the Palestinian Authority, President Biden will postpone his travel to Jordan and the planned meeting with these two leaders and President Sisi of Egypt," the official said on Tuesday. "The President sent his deepest condolences for the innocent lives lost in the hospital explosion in Gaza, and wished a speedy recovery to the wounded."

The head of the political bureau of the Palestinian movement Hamas, Ismail Haniyeh, assigned additional responsibility for the deadly attack on a hospital in the Gaza Strip on the United States, which provides assistance to Israel.

The Israeli military was not involved in the strike on a hospital in the Gaza Strip, Israeli Prime Minister Benjamin Netanyahu said on Tuesday.

The Palestinian Hamas movement is prepared to immediately release all civilian hostages if a ceasefire is established, member of the political bureau of Hamas, Musa Abu Marzouk, said on Tuesday.

"Yes, if a ceasefire is established, we will have no interest in holding these people [hostages]," Marzouk told Al-Jazzera, answering a question whether Hamas would be ready to immediately release civilian hostages under a ceasefire.
