A helicopter of civil security flies over Dammartin-en-Goele, north-east of Paris, where two brothers suspected of killing 12 people in an Islamist attack on French satirical newspaper Charlie Hebdo held one person hostage as police cornered the gunmen on January 9, 2015. Explosions were heard at the site where the hostage drama unfolded at a printing business in the small town of Dammartin-en-Goele, only 12 kilometres (seven miles) from Paris’s main Charles de Gaulle airport, journalists reported.
