Since Islamic State’s hold on Iraq and Syria has weakened in recent years the group has sought to expand into new territories, including Africa.

IS insurgents have reportedly killed thousands, including children, and displaced thousands more in Mozambique, Mali, and Somalia, among other territories across the continent.

It is believed that IS franchises its brand to local militant groups, providing support, claiming responsibility for deadly attacks, all while spreading its influence in these new territories.

Charmaine Cozier asks if Africa is a new power base for the Islamic State group?

Peru has suffered one of the highest excess death levels in the world. The government failed to take account of the structure of society and the needs of its people in its response to the pandemic. A culture of corruption and political turmoil are persistent themes that have led to an underfunded health system and a lack of focus how Peruvian people would be able to cope during the dark months of a deadly pandemic. Instead vast numbers of casual workers lost their jobs and started to trek home, taking the virus with them. Also remote communities were cut off by the freeze on transport and unable to get access to vital medical supplies, amid a dwindling supply of oxygen to treat them. We take a look at what lies beneath Peru’s terrible experience during the pandemic.

Donald Trump has moved out of the White House, he’s been banned from Twitter and suspended from Snapchat, Facebook and YouTube. Parler, a twitter alternative for conservatives, went offline after Amazon stopped hosting it. Amazon say this is because they found dozens of posts on the service which encouraged violence. All of this has raised questions about the power of tech companies and who should decide who’s voice is heard on social media. So this week Charmaine Cozier asks, has big tech gone too far in limiting free speech?
