Police in Belfast urge calm after a stabbing attack is captured in a graphic video and begins to circulate online, prompting calls for anti-immigration protests in Northern Ireland. Multiple outlets report that authorities appealed to the public to avoid unrest as far-right figures and groups call for demonstrations following the incident. The attack is described as a violent knife stabbing in Belfast. France 24 reports an allegation that the suspect is a Sudanese national, while other accounts focus on the existence of the video and the public reaction rather than additional identifying details. The incident comes amid heightened tensions around migration in Northern Ireland, with DW noting that last June there were riots related to migration. Coverage also emphasizes that police communications are aimed at preventing further escalation and maintaining public order. The outlets characterize the video as disturbing and cite police efforts to manage community responses while investigations continue. No single outlet provides definitive conclusions on motive or responsibility beyond reporting the alleged suspect described by France 24 and the ongoing police investigation.
