In Colombia, Juan Carlos Pinzon has been sworn-in as the new Defence Minister, with orders to give the final blow to the Farc rebel group. Mr Pinzon is an economist, a former deputy defence minister, and a close ally of President Juan Manuel Santos. He was brought in to replace Rodrigo Rivera, amid a growing perception that security gains are being reversed. Mr Pinzon has promised more innovation in tackling Marxist guerrillas and ending Colombia's 47-year conflict.
