BBC News - Giant escalator installed in Colombian city of Medellin: The Colombian city of Medellin has opened a giant outdoor escalator for residents of one of its poorest areas.
People living in the Comuna 13 district - which clings to a steep hillside - previously had to climb hundreds of steps to get home from the city centre.
The escalator is divided into six sections and ascends nearly 384m (1,260ft).
The mayor of Medellin says it is the first project of its kind in the world aimed specifically at the poor.
