CNN reported that “at least one US-manufactured precision-guided bomb” was used in the strike on the Gaza City school on Saturday.

“Footage of the aftermath filmed by CNN showed parts of an explosive device that Trevor Ball, a former US Army explosive ordnance disposal technician, confirmed were from a GBU-39 small diameter bomb,” the American broadcaster added, noting that the munition is manufactured by Boeing.

Fadel Naim, director of Al-Ahli Baptist Hospital in Gaza City, said that the facility “received dozens of bodies … others with amputations and severe burns and piles of shattered flesh and bones from those who could not be identified” following the use of “precision” weapons against the school.
