Police officers search the scene of a stabbing on Kinnaird Avenue in north Belfast, Northern Ireland, on June 9, 2026. Northern Ireland police said on June 9, 2026 they had arrested a man following what Prime Minister Keir Starmer branded a "sickening" stabbing in Belfast, with graphic video prompting protest calls from UK far-right figures. Video of the June 8, 2026 incident posted on social media networks shows a man straddling another man lying in a street and slashing him several times in the head and neck with a knife in what appears to be an attempted beheading.
