Rocket from Gaza appeared to go astray and hit hospital

Shortly before 7 p.m. Tuesday, a volley of rockets lit up the darkened sky over Gaza. Videos analyzed by the Associated Press show one veering off course, breaking up in the air before crashing to the ground.

Seconds later, the videos show a large explosion in the same area — the site of Gaza’s al-Ahli Arab Hospital.

Who is to blame for the fiery explosion has set off intense debate and finger pointing between the Israeli government and Palestinian militants, further escalating tensions in their two week-long war.

The AP analysed more than a dozen videos from the moments before, during and after the hospital explosion, as well as satellite imagery and photos. AP’s analysis shows that the rocket that broke up in the air was fired from within Palestinian territory, and that the hospital explosion was most likely caused when part of that rocket crashed to the ground.

A lack of forensic evidence and the difficulty of gathering that material on the ground in the middle of a war means there is no definitive proof the breakup of the rocket and the explosion at the hospital are linked. However, AP’s assessment is supported by a range of experts with specialties in open-source intelligence, geolocation and rocketry.

“In the absence of additional evidence, the most likely scenario would be that it was a rocket launched from Gaza that failed mid-flight and that it mistakenly hit the hospital,” said Henry Schlottman, a former U.S. Army intelligence analyst and open-source intelligence expert.

The AP reached its conclusion by reviewing more than a dozen videos from news broadcasts, security cameras and social media posts, and matching the locations to satellite imagery and photos from before the explosion.

A key video in the analysis came shortly before 7 p.m. local time, when the Arabic-language news channel Al Jazeera was airing live coverage of the Gaza City skyline. As a correspondent speaks, the camera pans to zoom in on a volley of rockets being fired from the ground nearby.

One of the rockets appears to veer from the others, away from the distant lights of Israel and back toward a darkened Gaza City, where electricity has largely been cut. The camera follows the light from the rocket’s tail as it arches in the sky upwards and toward the left. Suddenly, the rocket seems to fragment, and a piece appears to break off and fall. Another fragment shoots sharply up and to the right, blazing before it explodes in a fireworks-like flash, leaving a brief trail of sparks.

A small explosion is then seen on the ground in the distance, followed two seconds later by a much larger blast closer to the camera. The corner of the scroll at the bottom of the live broadcast reads 6:59 p.m. Gaza time.

Using maps and satellite imagery, the AP was able to match the view of the explosion from Al Jazeera’s live camera feed to an upper floor of the building that houses Al Jazeera’s Gaza bureau, which is less than 1.5 kilometres from the al-Ahli Arab Hospital. Using other buildings visible in the frame, the AP was able to confirm that the larger explosion seen at 6:59 p.m. was in the precise direction of the hospital.

A second video, taken from a camera inside Israel at the exact time as the Al Jazeera footage and obtained by the AP, shows a barrage of at least 17 rockets being launched from inside Gaza before a large explosion lights up the horizon on the Palestinian side of the border. The camera is on a building in Netiv Ha’asara, an Israeli community footsteps from the border wall, and faces southwest, confirming that the rocket launches and explosion were in the direction of Gaza City.

A third video by Israeli news station Channel 12 — taken from a camera on the upper floor of its building in Netivot, a town about 16 kilometres southeast of the hospital in Gaza City — also captured the barrage of rockets fired at 6:59 p.m.

Seen together, the three videos show multiple rockets were launched from inside Gaza before one appears to have come apart in midair about three seconds before the explosion at the al-Ahli Arab Hospital.

At 7 p.m., one minute after the explosion, Hamas’ military wing al-Qassam Brigades said in a post to its Telegram channel that it “fired at occupied Ashdod with a barrage of rockets.” Ashdod is an Israeli coastal city about 50 kilometres north of Gaza.

Minutes later, Islamic Jihad, a militant group that works with Hamas, also posted on Telegram that it had launched a rocket strike on Tel Aviv in response “to massacre against civilians.” Over the next hour, there were five more posts from the militant groups announcing rocket attacks against Israel.

Israel’s military has repeatedly said it did not strike the hospital and blamed an errant rocket fired from within Gaza by the Islamic Jihad. Israel’s assessment, backed by U.S. intelligence and President Joe Biden, also cited the lack of both a large crater and extensive structural damage that would be consistent with a bomb dropped by Israeli aircraft.

Hamas calls Israel’s narrative “fabricated” and accuses it of punishing the hospital for ignoring a warning to evacuate two days earlier, though it has not released any evidence to support its claims.

Hamas spokesperson Ghazi Hamad told the AP the group would welcome a United Nations investigation into the cause of the blast.

AP ran its visual analysis by a half-dozen experts who all agreed the most likely scenario was a rocket from within Gaza that veered off and came apart seconds before the explosion.

Andrea Richardson, an expert in analyzing open-source intelligence who is a consultant with the Human Rights Center at the University of California, Berkeley, School of Law, said specific landmarks visible in the videos show where the rockets were launched.

“From the video evidence that I have seen, it’s very clear that the rockets came from within Gaza,” said Richardson, a human rights lawyer and experienced war crimes investigator who has worked in the Middle East.

While still potentially lethal, the explosive warheads carried by the homemade rockets used by militants in Gaza can be relatively small when compared with the munitions used by large militaries like those of the U.S. and Russia. With Gaza’s borders and ports blockaded for the past decade, militants often build rockets and launch tubes inside Gaza using whatever parts and materials they can scavenge, including underground water pipes.

Justin Crump, a former British Army officer and intelligence consultant, said the failure rate of such homemade rockets is high.

“You can see obviously it fails in flight, it spins out and disintegrates, and the impacts on the ground follow that,” said Crump, CEO of Sibylline, a Londonbased strategic advisory firm. “The most likely explanation is this was a tragic accident.”
