A stray dog captures Chile's heart

Springtime is normally dry and sunny in Santiago, Chile. But the city has recorded its wettest October on record in the first week of the month when around two inches of rain fell in just a single day. Heavy rainfall high up in the Andes mountains rushed down into Santiago's Mapocho River, turning it from a sedate flow into a torrent. And among all the chaos, there was one rescue that kept the public riveted for hours, and later became an unlikely global hero as Jane Chambers reports.
