Colombia's President Gustavo Petro claims to have been the target of a plot to down his plane with missiles by "big mafias" irate at his government's attempts to hunt them down. "They want to shoot a missile at my plane... not one, but two missiles. We know who they are," the South American country's first-ever leftist president tells during the swearing-in of the new National Police Director, General Carlos Triana, at the General Santander Police School in Bogota.
