Around 8:45pm on 13 July, 2010, a few of the women of the Abu Said family in the northern Gaza Strip were enjoying the cool of the evening in the courtyard in front of their house. They heard a muffled shooting sound, followed soon after by another, and then by a loud buzzing noise, as if a swarm of insects was approaching at full speed. Vittorio Arrigoni reports from the occupied Gaza Strip.
