At least 500 people were killed when an airstrike from Israel hit Al-Ahi Baptist Hospital in Gaza, on Tuesday.
According to Palestinian health officials, the hospital was packed with wounded patients and others seeking shelter.
Several hospitals in Gaza City have become refuges for hundreds of people, hoping they would be spared bombardment.
Israel has launched massive strikes into Gaza since Hamas crossed into the country on October 7, killing over 100 and taking about 200 hostage.
The Middle East country had declared Operation Iron Sword and vowed to turn Gaza into rubble.
Israeli military spokesman Rear Adm. Daniel Hagari, said there were still no details on the hospital deaths.
“We will get the details and update the public. I don’t know to say whether it was an Israeli air strike.”
Moments later, an IDF source blamed the incident that has sparked global outrage on Hamas, saying the group mistakenly targeted the hospital.
