Sir David Amess, a member of parliament for the ruling Conservative Party, has been killed in a stabbing attack in Essex, England. A 25-year-old man has been arrested on suspicion of murder. Also on the programme: a deadly suicide attack on a mosque in Kandahar, Afghanistan; and what baby frogs can teach us about the healing power of algae.
