Israel said it killed two Hamas commanders — fulfilling its goal — in its strike on Rafah, which also killed 50 Palestinians and injured at least 249 others in a displaced persons camp on Sunday.

The explosion and subsequent inferno at the camp remains under investigation, IDF chief spokesperson Rear Adm. Daniel Hagari told reporters Tuesday.

Hagari did not confirm reports of tanks in Rafah, but ABC News has confirmed there are Israeli tanks in central Rafah, according to an eyewitness report.

Days after a deadly strike on Rafah killed 50 Palestinians and injured at least 249 others, a father of five who lost his wife told ABC News his family fled from Beit Lahia to Deir al-Balah — in the south of Gaza — before heading to Rafah for safety.

"One of my disabled sons had his leg amputated and my wife was killed. What injustice is this?" Murid Saadi Agha told ABC News. "There is no justice in the world. Israel is above all the law."

"I hold America and Israel responsible. We are innocent," he said.

Three of Agha's children have already lost limbs in the war.

"After sunset, my wife and I were sitting here outside the shelter with our neighbors, and my disabled son was feeding his other disabled brother, who is older than him. Even the Indomie that he was eating was still here," he said, describing the aftermath of the deadly Rafah strike.

"There was a very intense explosion. My wife declared once that the shrapnel entered her chest and killed her. I went to my sons and found that one of them had an amputated foot, as the shrapnel entered from the top and from the side. There were many martyrs here. It was a massacre," he said.

Strikes on Rafah have continued, barely 48 hours since an Israeli airstrike near a camp of displaced people killed 50 and injured 249 others. The continued offensive comes as at least 36,050 Palestinians have been killed since Oct. 7 and 81,026 others have been injured.

The Israel Defense Forces said their ongoing Rafah operation is "precise."

The Israeli military's deadly airstrike in Rafah on Sunday night hit an area about 650 feet away from the boundary of an IDF-designated "humanitarian area," according to an ABC News analysis of geolocated images and the IDF's statements and maps.

The U.N. Security Council will hold an emergency meeting later Tuesday to discuss Sunday's strike on Rafah.

At least 1 million people have fled Rafah in the past three weeks, according to the United Nations Relief and Works Agency for Palestine Refugees in the Near East.

The Kuwait Specialized Hospital in Rafah, one of its largest, announced that the hospital had been out of service due to the expansion of the Israeli military operation on the city and the repeated and deliberate targeting of the hospital's vicinity, hospital's director Suhaib Al-Hams said Sunday.

The Israeli occupation repeatedly targeted the hospital, the most recent of which was targeting the hospital gate, which led to the death of two of the staff working there, as well as the injury of five members of the medical staff in a previous targeting, Al-Hams said in a press statement received by Sanad News Agency.

"We announce that the Kuwait Specialized Hospital has been out of service and the working medical teams have been transferred to the field hospital that is being prepared in the Al-Mawasi area," Al-Hams said.

An Israeli government official said the Israeli Prime Minister’s Office wasn’t informed that President Joe Biden’s Friday remarks would include a permanent end to the fighting.

“If you listen to what Biden said, you come to the impression that we agree to a permanent cease-fire without, or, without our conditions being met, and that's not the case,” the official said.

The official said the Israeli Prime Minister’s Office, including Prime Minister Benjamin Netanyahu, was informed 30 minutes before that Biden was giving a speech. The official said Netanyahu was told that the speech would focus on the hostages, with no mention of implementing a permanent cease-fire.

A senior U.S. official said the Biden administration "engaged with the Israelis at multiple levels before the president delivered the speech." The official said the U.S. specifically engaged with the Israeli Prime Minister's Office and the Israeli war cabinet.

The official also pointed to when Biden said in his speech that it was a proposal that the Israelis agreed to. The official noted that Netanyahu himself said that it was an Israeli proposal.

An Israeli official and two other Israeli sources who are familiar with the matter told ABC News that what Biden presented is indeed the outline of the Israeli proposal. The sources said the proposal was approved by all war cabinet members, including Netanyahu, and sent to the mediators earlier in the week.

The sources added that there are “interpretation gaps,” referring to the way the outline was presented by Biden.

Biden presented on Friday what he said was an Israeli proposal to draw the war in Gaza to a close.

Biden said the deal had been transmitted to Israel and Hamas, through Qatar.

The president said the first phase would last for six weeks and include a "full and complete cease-fire, a withdrawal of Israeli forces from all populated areas of Gaza [and] release of a number of hostages." Palestinians would also be able to return to their homes and 600 trucks of humanitarian aid would be delivered to Gaza every day.

The second phase would include a release of all remaining living hostages and the temporary cease-fire would become a permanent cease-fire with Israel withdrawing all forces from Gaza "as long as Hamas lives up to its commitments," Biden said.

In phase three, there would be a major reconstruction of Gaza.
