If you're talking about the bombing of the courtyard of the European hospital, no the IDF reason given has not been debunked as fake.
They found 2 Hamas senior leaders hiding under the hospital plus the bodies of other unidentified Hamas militants and a network of tunnels, rooms and weapons. It was a Hamas control centre, as has already been mentioned on these threads several times.
Reuters: The Israeli army said on Sunday it had retrieved the body of Hamas' military chief Mohammed Sinwar in an underground tunnel beneath a hospital in southern Gaza, following a targeted operation last month.
Another senior Hamas leader, Mohammad Shabana, commander of the Rafah Brigade, was also found dead at the scene along with a number of other militants, who are still being identified, said IDF spokesperson, Brigadier General Effie Defrin.
Israeli forces gave a small group of foreign reporters a tour of the tunnel that had been uncovered beneath the European Hospital in Khan Younis, which Defrin said was a major command and control compound for Hamas.
"This is another example of the cynical use by Hamas, using civilians as human shields, using civilian infrastructure, hospitals, again and again," said Defrin.
"We found underneath the hospital, right under the emergency room, a compound of a few rooms. In one of them we found, we killed Mohammed Sinwar," he said.
