Police in London are preparing for a major demonstration as protesters call for the immediate release of hostages held in Gaza. The march, organized by a coalition of groups, will proceed through central London and end at the prime minister's residence. The event follows a large protest the previous day, which resulted in hundreds of arrests. Among the participants is Noga Guttman, whose cousin was recently featured in a distressing video released by Hamas. Organizers emphasize that the demand for the hostages' release transcends politics and is fundamentally a human concern.
