We hear why Twitter has hidden one of President Trump’s tweets from his timeline. The ´óÏó´«Ã½â€™s Rob Young talks us through the social network’s argument that the message in question ‘glorified violence’. And we consider the implications for other social networks with Frederike Kaltheuner, technology policy fellow at Mozilla. Also in the programme, the UN has warned that a swarm of locusts ravaging crops in Ethiopia, Kenya and Somalia is classified as dangerous. The ´óÏó´«Ã½â€™s Michael Kaloki tells us why food security in the region could be threatened. Plus, we examine the promise of an undersea cable being laid around Africa with connections in 16 countries. Paul Gabla of Alcatel Submarine Networks explains what’s inside an underwater cable. Edward-John Bottomley of Business Insider in South Africa discusses why people there are excited for the new cable. And Captain Jeffrey Sanders of US cable giant SubCom describes the complex precision process involved in actually laying an underwater cable.
