Six hostages who hid in a supermarket freezer during January's Islamist attacks in Paris have sued French media for broadcasting their location live during the siege. Amedy Coulibaly stormed into the Hyper Cacher Jewish store, killing four and taking others captive before being shot dead in a hail of gunfire by French special forces. The heavily televised events in eastern Paris came two days after Cherif and Said Kouachi shot 12 people at the offices of satirical magazine Charlie Hebdo. Patrick Klugman, a lawyer representing the six survivors, said images broadcast from Hyper Cacher on January 9 'lacked the most basic precautions' and endangered those still alive inside.

Terrorist: Amedy Coulibaly slaughtered customers during the siege at the Hyper Cacher store. Lawyers claim French media endangered the lives of hostages hiding a freezer by revealing their location live on air . He singled out French 24-hour news channel BFMTV which revealed live on air that the group - including a three-year-old child and a one-month-old baby - was hiding  in the freezer. They had been taken to the cold room by one of the supermarket's employees. 'The working methods of media in real time in this type of situation were tantamount to goading someone to commit a crime,' Mr Klugman told AFP Thursday, roundly criticising coverage by other outlets of the movements by security forces during the standoff. The lives of those hiding 'could have been at risk if Coulibaly had been aware in real time what BFMTV was broadcasting,' Klugman said. He added that the jihadist was following the coverage of his raid on different channels and had been in contact with BFMTV journalists. The lawsuit charges media  with endangering the lives of others by deliberately ignoring security protocols, which carries a maximum penalty of a year in prison and a €15,000 (£11,000) fine. Extraordinary pictures emerged in the days after the siege showing the hostage huddled together for warmth amid cardboard boxes of food inside the freezer. Defying terror: Hyper Cacher reopened last month with a vow to 'show that life is stronger than barbarity' One woman is seen cradling her child, while in another image a hostage sends a text message to a loved one. Hearing shots, shoppers at the back of the store fled downstairs to the storeroom where they huddled together in temperatures of -3C (27F). Fearing they would not escape alive, they made what they believed would be their last calls to family to tell them they loved them. One man, known only as Ilan, was with his young son and quickly removed his jacket and wrapped him in it as they cowered in freezer for nearly five hours before Coulibaly was shot dead. The Kouachi brothers were also killed after three days of attacks that killed a total of 17 people and deeply shocked France and the world. Hyper Cacher finally reopened last month with a vow to 'show that life is stronger than barbarity'.
