Many residents of Gush Dan settlement in Tel Aviv got annoyed from the sound made by the Israeli drones, according to Yedioth Ahronoth.

Dozens of Israelis living in that area wondered about a strange sound they heard to discover later that this sound is for the Israeli drones flying in the sky.

Meanwhile, the spokesman of the Israeli army said that "the matter is linked to a multi-day maneuver carried out by the Israeli army which aims to maintain high levels of readiness for any emergency that may occur and to save the security in the region."

However, the Israeli army may do such maneuvers in uninhabited areas.

The sound of the drones is heard due to the lack of flights in Bin Gurion airport which was full of planes' sounds before the outbreak of coronavirus.
