The Israeli army withdrew from al-Shifa hospital in the city of Gaza during the night, some two weeks after the start of its military operation there, according to Palestinian reports from Monday morning.
Local media reported that the operation had caused severe destruction to the buildings of the largest medical complex in the Gaza Strip.
Around 300 bodies were found in and around the hospital, according to the Palestinian civil defence force, which is controlled by the militant organization Hamas.
The World Health Organization (WHO) reported that 21 patients have died since the start of the siege on March 18.
Israeli Prime Minister Benjamin Netanyahu described the operation at al-Shifa hospital on Sunday evening as a great success. He spoke of a "precise and surgical" military operation. More than 200 terrorists had been killed and hundreds had surrendered, Netanyahu said.
According to Israel, Hamas had once again set up fighting and command positions in the extensive area, after the Israeli military had already stormed the hospital in November. Israel accuses Hamas of systematically misusing medical facilities for military purposes. Hamas denies this.
Israeli army spokesman Daniel Hagari said a week ago that Hamas and Islamic Jihad fighters had barricaded themselves in various departments of the hospital.
Hamas was firing at Israeli troops from the emergency room and the maternity ward, he said, adding that they had fired mortar shells and caused serious damage and fires in the hospital complex.
Hamas' military wing has claimed responsibility for several attacks on Israeli troops in the area of al-Shifa hospital in recent days.
The hospital was destroyed in the operation as concerns grow about the catastrophic humanitarian situation in Gaza.
With famine looming in the coastal strip, three ships carrying hundreds of tonnes of aid for Gaza have almost reached their destination after two days at sea.
The Open Arms vessel from the aid organization of the same name was only around three nautical miles off the coast of the coastal strip on Monday, Freighter Jennifer and tugboat Ledra Dynamic were some 15 nautical miles away, according to Marinetraffic shipping site.
The convoy left Cyprus on Saturday and its cargo was expected to be unloaded on Monday, as Cypriot President Nikos Christodoulidis said on the sidelines of a press conference.
Hpwever, unloading the cargo is one of the biggest challenges for aid brought by ship given the lack of a suitable port in Gaza, and the shallow waters of the coast.
Nonetheless, Christodoulidis said further deliveries would follow and a pier is to be operational by mid-April to make unloading aid easier.
The war was triggered by attacks on Israel in October by Palestinian Islamist organization Hamas and other extremists which killed some 1,200 people in southern Israel.
Israel seeks to eliminate Hamas but faces growing criticism at home and abroad given the soaring number of civilian casualties and desparate situation in Gaza.
More than 32,782 people have been killed and at least 75,298 injured in Gaza according to the health authority in the Strip.
As talks continue under mediation to bring about a ceasefire, a high-ranking Israeli delegation left Cairo on Monday afternoon, according to informed sources at Cairo airport.
They had held nearly two days of talks about a ceasefire in Gaza and the release of further hostages held in Gaza and Palestinian prisoners in Israeli jails, according to the sources.
Qatari television channel Al-Jazeera reported earlier that the indirect negotiations did not lead to significant progress in discussions aiming to bring about a pause in the fighting.
Later on Monday, representatives of Israel and the United States are to meet online for talks on Israel's planned ground offensive against the city of Rafah in the south of the Gaza Strip.
The meeting will take place as a videoconference via a secure connection. Washington opposes a large-scale ground offensive in Rafah because of the prospect fo mass civilian casualties, as at least 1 million people have fled there from fighting elsewhere in the strip.
Meanwhile critics of Israeli government policy have set up more than 100 protest tents in front of the parliament in Jerusalem.
The tents are part of a four-day protest action in the city, Israeli media reported on Monday.
Protests against Netanyahu and the Gaza war are currently attracting crowds, after tens of thousands of people demonstrated in Israel for the second day in a row on Sunday.
Participants near the parliament building demanded the resignation of the government, a new election and a swift deal to release the hostages held in Gaza.
In what some feared could lead to further escalation abroad, a general from Iran's Islamic Revolutionary Guard Corps was killed in what Iran said was an Israeli strike on its consulate building in damascus
The Syrian Observatory for Human Rights (SOHR) confirmed the killing of a leader of the Quds Force, one of five branches of the IRGC. It said two Iranian advisors and five IRGC members were also killed in the attack, according to preliminary information.
