Hamas is expected to release a fifth batch of Israeli captives on Saturday as part of the hostage release and ceasefire deal, as uncertainty looms over the future of the agreement. Israel is pressuring mediators to secure the release of a mother and her two young sons, who were not released in violation of the deal. The fate of the deal is dependent on the progress of US President Donald Trump's proposal to relocate Palestinians from Gaza. Talks for the second phase of the deal have been delayed, causing concern for the families of hostages who are not set to be released until the next phases.
