Mexico quake: Volunteers turned away, search dog hailed as hero

There are so many volunteers helping in ruined Mexican towns that many are now being turned away. Volunteer Jorge Torres has been visiting the town of Pilcaya, near the epicentre of the 7.1 quake. He says 85 percent of the houses are badly damaged and there's about 8,000 people without proper shelter. He tells us students with cancelled classes are flocking to the devastated areas to offer help.
