Four people including a policewoman are in custody over links to the attacks that terrorised Paris earlier this year, French police and security officials said.

Four men are facing preliminary charges on suspicion of links to a gunman involved in France’s deadliest terrorist attacks in decades.

The shooting of a jogger in a Paris suburb on the same day as the Charlie Hebdo massacre has been linked to the gunman who killed a policewoman and four hostages at a kosher supermarket, a prosecutor said.

Police union representative Christophe Crepin has told LCI television that it appeared that the gunman who took hostages at a kosher market in Paris has died after police stormed the building.

The two brothers behind the Charlie Hebdo terror attacks in Paris have been killed, according to reports, as police stormed both siege scenes.
