On Saturday, 30th March, at 22:10 a fire on the third floor of an apartment building in Aubervilliers spread to the fourth floor through the lift. Three people were killed and 13 injured, of whom four seriously. Twenty minutes later a fire killed five children in a house in Saint-Quentin. France has introduced a law to require smoke detectors in existing homes by 2015. The next step has to be sprinklers.
