Footage of the explosion at al-Ahli hospital suggests it was caused by a missile fired from Gaza, open source analysts said.
Tuesday’s strike killed hundreds of Palestinians, with horrific images of the aftermath showing victims lined up in body bags.
The Hamas-run territory’s health ministry blamed Israel for the attack, with several Arab leaders condemning the country for the attack.
The Israel Defense Forces (IDF) denied the allegations and in turn pointed the finger at Islamic Jihad, a group allied with Hamas terrorists.
Daniel Hagari, an Israeli military spokesman, said the country’s drone footage showed the rocket used in the attack “does not match any of the (Israeli) Air Force’s munitions.” “.
Several independent analysts reviewed footage of the explosion and said their investigations confirmed the IDF’s denial.
Some said the massive explosion appeared to have been caused by a dud projectile from a large rocket barrage launched from northern Gaza.
Islamic Jihad denied that any of its rockets were involved in the explosion, saying it had no activity around Gaza City at the time, but analysts noted that it had already used large rockets of the type involved.
Open source intelligence (OSINT) is defined as intelligence produced by the collection, evaluation, and analysis of publicly available information.
One of the tools used is geofencing, which uses landmarks and other clues to gather information about a specific target or location.
GeoConfirmed, which is run by volunteers, said the strike was likely caused by “a missile launched by a Palestinian group (which) exploded in midair (reason unknown) and a piece fell on the hospital , causing an explosion.
The group cited several alleged clips of the explosion from different sources and claimed that “the geolocation and timing of the images are conclusive.” However, they said their findings did not constitute “proven facts.”
“This does not mean they are THE truth, just what we think is most likely based on our geolocations (facts) and logic/reason,” they wrote on Twitter.
“We are geolocators, not official investigators… To be sure of what really happened, different official investigations are necessary. »
Separately, Evan Hill, who conducts open source investigations for the Washington Post, said video taken during a live broadcast “appears to show a rocket interception” followed by an explosion at the hospital.
It comes as US President Joe Biden ordered his own national security team to investigate what happened.
The White House released a statement from Mr. Biden in which he denounced the “terrible loss of life” caused by the explosion, but did not assign responsibility to any party.
The carefully worded comment was issued on Tuesday as Mr. Biden traveled to the Middle East for talks in Israel.
His trip to Jordan for a summit on humanitarian aid to the Palestinians, which was to take place after his visit to Tel Aviv, was canceled.
Mr Biden was due to meet King Abdullah of Jordan, Egyptian President Abdel Fattah El-Sisi and Palestinian Authority President Mahmound Abbas.
“There is no point in talking now about anything other than stopping the war,” Jordanian Foreign Minister Ayman Safadi said on state television.
