"At least four people were killed by a gunman who took hostages in a kosher supermarket in eastern Paris, a police source told Reuters on Friday...
There were unconfirmed local media reports that the man was the same as the one suspected of killing a policewoman in a southern suburb of Paris on Thursday.
A police source had told Reuters earlier he was a member of the same jihadist group as the two suspects in Wednesday's attack at weekly newspaper Charlie Hebdo."
