Police on Thursday discovered the bodies of five babies in a house in southwestern France, a source close to the case said, in what appears to be the country's worst incident of infanticide in five years.

After the body of a newborn was found in a thermal bag earlier in the day, officers "discovered four more bodies of babies during their search" at the house in Louchats, near the city of Bordeaux, the source said, confirming a report by French television channel iTele.

Wine professionals declared themselves "pleasantly surprised" with the 2012 Bordeaux vintage but demand from China was expected to be weak due to losses on 2010 wines.

China is currently Bordeaux's biggest market in terms of volume and second in value, but Chinese buyers were expected to stay away this time.
