Almost four million turn out for unity rallies across France

It was a show of solidarity never before seen in France. Almost four million people have turned out in Paris and other cities for unity marches after the murder of 17 people in three separate terrorist attacks. Officials say attendance in Paris was more than two million and the figure was at least 3.7 million nationwide. This breaks the previous record for the largest rally in France: the liberation of Paris after World War Two.
