Zanana

[6] Since 2000, Israeli drones have commonly been present in the sky over the Gaza Strip,[7] where they were initially used for surveillance; missile strikes targeting people and infrastructure first occurred in 2004 and proliferated in 2006 after Israel's unilateral disengagement.

[8] In addition to surveilling and killing both militants and civilians,[7] with a majority of those killed being civilians,[6] the drones produce a near-constant buzzing noise audible from the ground,[6][7] disrupt satellite television reception,[3][9] and create a psychological impact involving fear among the Palestinian population in Gaza.

[3][6][8][10] Increases in volume generate fear of military escalation, and the consistent buzzing is disruptive to sleep.

A rough literal translation of the Arabic word zanana (also transliterated zenana) is "buzzing sound" or "noisemaker".

[7][3] In Egypt, which borders Gaza and has influenced its culture, zenana is a slang term that refers to a nagging wife.
