Putting South Sudan's Economy Back on Track

We go to Juba, the capital of South Sudan, to find out whether the country can rebuild its economy. We tell you why large airports like London's Heathrow might be tempted to buy the 'Death ray', which is a military system designed to take down drones. Plus, we find out more about the killing of 11 people, many of them soldiers, in the island nation of Cape Verde.
