Thousands of anti-racism demonstrators rallied across the UK on Saturday in response to recent far-right riots triggered by misinformation linking a Southport knife attack, which killed three children, to a Muslim immigrant. Protests took place in cities including London, Glasgow, Belfast, and Manchester, with no significant confrontations occurring. The Stand Up to Racism group organized these events, aiming to counteract the wave of anti-immigration sentiment. Authorities reported over 700 arrests related to the riots, with ongoing investigations into racially motivated hate crimes, including a petrol bomb attack on a mosque in Northern Ireland. The protests were largely peaceful, emphasizing messages of inclusivity and support for refugees. Efforts to address online disinformation, which fueled the unrest, are ongoing, with calls for social media companies to act swiftly to remove harmful content.
