For those who want to read it without the paywall, here are the important parts:

Multiple synchronized videos show a projectile, previously identified by Israeli officials as a Palestinian rocket, launching from Israel and detonating near the Israel-Gaza border.

The footage has become a widely cited piece of evidence as Israeli and American officials have made the case that an errant Palestinian rocket malfunctioned in the sky, fell to the ground and caused a deadly explosion at Al-Ahli Arab Hospital in Gaza City.

Numerous media outlets have shown the video footage and several have cited it as evidence that a Palestinian rocket hit the hospital.

But The Times concluded that the missile in the video was never near the hospital. It was launched from Israel, not Gaza, and appears to have exploded above the Israeli-Gaza border, at least two miles away from the hospital.

To trace the object in the sky back to Israeli territory, The Times synchronized the Al Jazeera footage with five other videos filmed at the same time, including footage from an Israeli television station, Channel 12, and a CCTV camera in Tel Aviv. These different videos provided a view of the missile from north, south, east and west. Using satellite imagery to triangulate the launch point in those videos, The Times determined that the projectile was fired toward Gaza from near the Israeli town of Nahal Oz shortly before the deadly hospital blast. The findings match the conclusion reached by some online researchers.

The Times cannot independently identify the type of projectile that was fired from Israel, though it was launched from an area known to have an Iron Dome defense system.
