\u201cIt becomes scary when you see people that would normally smile at you - and all of a sudden you see so many people on the streets making those kind of chants. And you think, 'wow, what has been going on underground? This is the city that I used to know. Why should I now be extra watchful? What exactly is going on?'\u201d - Toyyib Adelodun, Nigerian migrant in the UK\n \nThe world watched in shock as police cars were destroyed and shops and properties belonging to foreign nationals targeted in the UK, earlier this month.\n \nThe riots were triggered by the killing of three girls at a Taylor Swift-themed dance event for children in Southport, northern England.\n \nFalse rumours were spread on social media that the teenager charged with the murders was a Muslim migrant.\n \nThere were similar events in the township of Soweto in South Africa recently.\n \nShops belonging to African immigrants were forced to shut down, after a foreign national was accused of attacking a local resident.\n \nAlan Kasujja attempts to find out if these are isolated incidents or if there is a political ideology driving them.\n \nGuests: Professor Bongani Ngqulunga, Toyyib Adelodun and Wallace Musonda
