30:T696,Depuis le 7 octobre 2023, les bombardements pleuvent sur Gaza. C'est tout un peuple qui est massacré. C'est tout un pays qui est mis à genoux. Ecoles, hôpitaux, universités, tout est méthodiquement détruit sous les ordres du gouvernement d’extrême-droite de Benjamin Netanyahou qui continue sa fuite en avant criminelle. Mais comment rendre compte de l'ampleur d'un tel massacre ? Une méthode possible est l'analyse d'images satellitaires. Et c'est précisément la méthode qui a été employée par l'[UNOSAT](https://unosat.org/), le Centre satellitaire des Nations unie. Pour ce faire, l'UNOSAT a mobilisé 8 jeux d'images satellites s’échelonnant du 15 octobre 2023 au 6 juillet 2024 pour y identifier méticuleusement, date par date, les dégâts causés par les bombardements et l'incursion de l'armée israélienne. Le bilan est accablant : 46 223 structures détruites, 18 478 structures gravement endommagées, 55 954 structures modérément endommagées et 35 754 structures probablement endommagées. Au total, c'est près de 156 409 structures qui ont été détruites, soit environ 63 % de l'ensemble des structures de la bande de Gaza. Après la guerre, tout sera à reconstruire. La bilan est édifiant, donc. La réponse populaire doit être à la hauteur du drame qui se joue à Gaza. Solidarité sans failles avec nos frères et nos sœurs palestiniens qui se battent peur leur liberté. Mobilisation générale pour une paix juste et durable entre Palestiniens et Israéliens. - Source : [unosat.org/products/3904](https://unosat.org/products/3904) - Code source : [observablehq.com/@neocartocnrs/gaza](https://observablehq.com/@neocartocnrs/gaza)31:T1093,map = { let hovereId = null; //const container = yield html`
