Samuel Williams, a student at the University of Oxford, has been identified as the individual who led a controversial chant at a recent pro-Palestine demonstration in London. The chant, which included the phrase 'put the Zios in the ground', has been widely condemned and is under investigation by the Metropolitan Police. Williams, who has a history of student activism and has participated in several campus protests, was seen at the event wearing a military-style jacket and waving a fake gun. The University of Oxford and the Union of Jewish students have both issued strong statements denouncing the chant and calling for decisive action in response to the incident.
