According to local hospitals, when the school in Nuseirat was struck on Sunday night, it was providing sanctuary to war-displaced individuals.
Israel has not responded, but it frequently accuses Hamas members of hiding in school premises, something the organization disputes.
Israel’s military has identified the four soldiers who were killed in the drone strike on a military base in the town of Binyamina on Sunday.
According to the emergency service, 61 people were hurt when it struck the canteen while it was packed for dinner.
According to the Israel Defense Forces, all of the troops murdered were 19 years old.
They were identified as Sergeants Alon Amitay, Yosef Hieb, Yoav Agmon, and Omri Tamari.
Hezbollah, which the US and the UK have classified as a terror organization, claimed it was reprisal for an Israeli attack that killed 22 people in Beirut, the capital of Lebanon, on Thursday.
It asserted that Sunday’s attack used “squadrons” of drones and was designed to evade air defenses.
The incident occurred on the same day that the United States said it would provide Israel with a new air defense system and the personnel to run it.
