Tensions flared near the G20 summit venue in Johannesburg as South African anti-immigration groups, including Operation Dudula and MK Party supporters, clashed with police. The protest took place about 1.5 km from the Nasrec Expo Centre, where world leaders were meeting. Two people were arrested as demonstrators demanded stronger action against undocumented immigration, accusing authorities of failing to address border control issues. South Africa has seen a rising influx of migrants in recent years, with deportations increasing by 18% in the latest reporting period.
