The scene shows a moment of respite and relative calm in Gaza: a crowd of people watching a football match in a school playground. A player fails to control a long pass from a teammate. The opposing goalkeeper gathers the ball and looks to launch it back up the pitch.

But just after he throws the ball, a deafening boom sends everyone present running for cover, including the person filming. “A strike! A strike!” someone screams.

The footage, broadcast by Al Jazeera, showed the moment of an Israeli airstrike next to the gate of al-Awda school in Abasan al-Kabira, east of the city of Khan Younis in Gaza, on Tuesday. As the person who was filming the match flees, they pass dead bodies and severely injured people among the debris.
