A French media outlet has been sued by six survivors of the Paris Jewish supermarket hostage crisis in January for broadcasting the situation live.
The lawsuit was filed on March 27 and a preliminary investigation was opened by the prosecutor's office on Wednesday, said Paris prosecutor's spokesperson Agnes Thibault-Lecuivre, CNN reported.
The media outlet, BFMTV, has been accused of endangering the lives of the hostages, who were hiding in a cold room during the attack, by broadcasting their location live during the siege.
BFMTV, in a statement on Friday, said one of its journalists "mentioned only once the presence of a woman hidden inside the Hyper Cacher, on the basis of police sources on the ground".
"Immediately, the chief editor felt that this information should not be released. It therefore has subsequently never been repeated on air or posted on-screen. BFMTV regrets that the mention of this information could cause concern to the hostages, as well as their relatives, that their lives were in danger," the statement said.
Gunman Amedy Coulibaly stormed the the Hyper Cacher Jewish supermarket on January 9, killing four people and taking others hostage.
He was killed in the police operation to end the siege.
The hostage crisis was the culmination of three days of terror in Paris that began with the January 7 shooting of 12 people at the offices of French satirical magazine Charlie Hebdo.
The two brothers blamed for that attack, Cherif and Said Kouachi, were killed on January 9 after a violent standoff at an industrial site.
The terror attacks claimed the lives of 17 people and put France on a heightened state of alert.
