Beware of satellite navigation apps.
In Brazil a couple driving a car have been shot when they followed their app to a street in Niteroi, a large city across the bay from Rio de Janeiro.
Instead of leading them to their tourist destination they found themselves in a notorious favela, in a street of the same name.
Regina Murmura, 70, and a travel agent, was killed in a hail of gunfire. Her husband, Francisco, 69, managed to drive away.
