In July 2018, a disturbing video began to circulate on social media. In it two women and young children are shown being led at gunpoint by a group of soldiers. The captives are blindfolded, forced to the ground and shot 22 times.

The government of Cameroon initially dismissed the video as ‘fake news’. But through open-source investigations – examining details such as buildings, shadows, and uniforms – BBC Africa found that the blame lay squarely on Cameroonian Forces.

From the 10th July to the 31st of October 1940 the skies above Britain were a battle zone. The German Luftwaffe launched large scale attacks aiming to reach London, they were held back and ultimately defeated by the Royal Airforce which included many nationalities. The bravery of the pilots – known as ‘The Few’ - cannot be disputed but is it really true that the average life expectancy of a spitfire pilot during the Battle of Britain was just four weeks, as is often claimed. Tim Harford and Lizzy McNeill look into the statistics and consider which of the armed forces had the highest death rate.

Those whose job it is to care – doctors, nurses, mothers even – face even more relentless demands on their compassion. Until one day some feel they cannot go on anymore.
