Since October 7, Israel has been using thunderous noise, triggering memories of Beirut’s devastating port explosion and spreading dread among the population.

Beirut, Lebanon – The first time Eliah Kaylough, 26, heard the thunderous blast, he was so terrified, he instinctively ran for cover. On Tuesday this week, he had just started his shift as a waiter at a restaurant on bustling Gemmayze Street in east Beirut when he was suddenly startled by the sound of a major blast.

For Kaylough, it immediately triggered memories of the massive port explosion in 2020 and he was terrified the city was either experiencing a new explosion or that it was under attack.

But as he was racing out of the restaurant, a man from a nearby shop stopped him and explained that Beirut wasn’t being bombed. The sound, Kaylough discovered, was a sonic boom, a thunderous noise caused by an object moving faster than the speed of sound.

Israeli jets have been increasingly triggering these sonic booms over Lebanon since October 7 last year, following the attack on southern Israel by Hamas. But the booms which sounded over Beirut on Tuesday were the loudest that had been heard in the city, several residents told Al Jazeera.
