Israeli forces on Wednesday raided the biggest medical complex, Gaza City's Al-Shifa hospital, one of a number of facilities that have been targeted by near-constant airstrikes for a little over a month now.

Global concern has flared over Israel's war and the thousands of war-wounded and displaced civilians inside the hospital, which has been deprived of electricity, generator fuel and essential medical supplies.

Here is a look at four of the major hospitals in the urban battle zone of Gaza City, in the north of the long-blockaded coastal Palestinian territory.

Al-Shifa Hospital
 

The Israeli army launched what it calimed "a targeted operation" overnight inside Al-Shifa, after days of heavy bombardment on the civilian-packed complex.

Troops raced through the packed corridors and wards and led more than 1,000 Palestinian men, their hands above their heads, into the courtyard, where tanks had moved in.

Fighting in recent days had forced the hospital to bury dead patients in a "mass grave", said the director of Al-Shifa, located in Gaza City's Rimal neighbourhood.

The hospital was built in 1946 during the British Mandate and has been extended since.

The UN World Health Organisation has said about 400 medical staff and caregivers worked there and 3,000 civilians had taken refuge from the war.

The Gaza government's deputy health minister told AFP on Sunday that an Israeli airstrike had "completely destroyed" the cardiac ward building.

Three nurses have been killed, said the UN Office for the Coordination of Humanitarian Affairs (OCHA) on Sunday.

"Essential infrastructure" including water tanks, maternity ward equipment and the medical oxygen storage centre had also been damaged, it said Sunday.

Similarly, an ambulance leaving the hospital was hit by a strike that killed 15 people in early November.

Al-Quds Hospital
 

Gaza City's Al-Quds Hospital -- with just 100 beds but recently sheltering thousands of displaced -- was evacuated on Tuesday, said the Palestinian Red Crescent Society.

"This comes after more than 10 days of siege, during which medical and humanitarian supplies were prevented from reaching the hospital," it said.

Opened in the early 2000s, the hospital had "become a threat to the lives of everyone inside" due to the war, complete power outage and the depletion of water and food.

Health staff and patients were taken to southern Gaza.

The Israeli army Monday reported firefights outside the hospital in which it said "21 terrorists" died.

OCHA earlier said that up to 14,000 people had taken refuge within the hospital complex since the start of the war.

This hospital was previously hit by Israeli airstrikes in the war of late 2008 to January 2009. Its emergency department and other wards were rebuilt with the help of French funding.

Indonesian Hospital
 

Opened in 2015, the Indonesian Hospital was financed by Jakarta and is located in Gaza's largest refugee camp, Jabalia.

It has a normal capacity of 110 beds, its director Atef al-Kahlot has said in media reports.

According to the Gaza government, at least 30 people were killed in the hospital by Israeli bombing.

Only weeks ago, targets near the hospital were bombed on October 28 and 29, after the Israeli army issued evacuation orders for northern Gaza, OCHA said.

Al-Rantisi Hospital
 

Al-Rantisi children's hospital is close to al-Shifa in western Gaza City.

In 2019, it was equipped with the territory's only paediatric oncology department, partly funded by a US humanitarian organisation.

The Israeli army entered Al-Rantisi on Monday and claimed to have evacuated its patients "to a safer hospital".

The director of all Gaza hospitals, Mohammed Zaqut, charged that the army had carried out "forced evacuations" of two paediatric hospitals, Al-Rantisi and nearby Al-Nasr, and left patients "on the streets without care".

The United Nations humanitarian chief on Wednesday demanded immediate action to "rein in the carnage".

"As the carnage in Gaza reaches new levels of horror every day, the world continues to watch in shock as hospitals come under fire, premature babies die..."

"An entire population is deprived of the basic means of survival. This cannot be allowed to continue," said Martin Griffiths.
