Overcrowding and lack of food, water, sanitation and basic hygiene are hastening the spread of disease in Gaza, according to the director-general of the World Health Organization (WHO). Wednesday is the sixth and potentially final day of the extended truce between Israel and Hamas, though negotiators are working toward another extension to get more hostages out of Gaza. Over the first five days of the truce, Hamas has released 81 hostages, primarily women and children. Israel has freed 180 Palestinians, mainly women and minors, from prison, many of whom were detained but never charged. Join CGTN's livestream for the latest updates.
