According to the France News24, numerous gunshots were fired at Riyadh. The Jerusalem post reports news of gunshots and explosions in front of the king's residence and sources on Twitter about a coup attempt and posted photos and videos of the situation. The king would have been dismissed as a precaution. The Jerusalem Post points out that it could not verify this information independently.
King Salman would have been removed and hidden in a protected military bunker.
Initially there was talk of a coup or terrorist attack but then the hypothesis of a drone over the building shot down by the security forces advanced.
