Did you read it? It says at the end "what happened at al-Ahli remains inconclusive"

Not to mention they say they scraped al Jazeera for other incident which is ironic here, because the claim is they misreport

And I will add that everything they said is only based on the videos... The impact on the ground was consistent with PIJ/Hamas rockets and not Israel missiles.

So I will rather believe U.S. Experts/Western intelligence (which since did not report otherwise)... so no Debunking at all:

Maher Arar is not an authority on this issue (same for me, same for you) as he is a telecommunications engineer. And all of his assumptions about missiles and air warfare in the article must have sources before used. Just like anything else, also in doppler equtions: garbage in, garbage out. But just look on the 2 videos he brings trying to claim it was a GBU-39 bomb:

One destroys an entire mosque in the past:

But the same left a 1 meter crater in the hospital???? Just nonsense.

As clearly stated in [3]: "More than half a dozen experts who independently reviewed imagery of the scene said the lack of major blast damage, such as collapsed buildings, as well as the relatively small size and shape of the crater, ruled out the possibility of the kind of airstrike Israel has carried out elsewhere in Gaza since Oct. 7."

You can go to Youtube yourself and look at the size of a GBU-39 explosion.
