France remains on its highest level of terror alert as Police in France have made seven arrests as they hunt for two named suspects over the deadly attack in Paris on staff at a satirical magazine. The seven, thought to be associates or family of the suspects, were detained in the towns of Reims and Charleville-Mezieres, as well as in the Paris area. France is mourning the 12 people killed when Charlie Hebdo was targeted by gunmen shouting Islamist slogans. Today has been declared a national day of mourning and a minute's silence will be observed at midday across the country and the bells of Notre Dame in the capital will toll.
