The Paris prosecutor's office says two people have been arrested on suspicion of helping provide guns to the man who attacked a kosher supermarket in January.

The man and woman were arrested Tuesday in northern France, nearly a year after the attacks on the Charlie Hebdo newspaper and kosher store left 17 people dead, the prosecutor's office said. The store attacker, Amedy Coulibaly, killed four people inside the market, and separately a policewoman, before dying in a shootout with police.

The prosecutor's office confirmed that one of those arrested is Claude Hermant, an acknowledged mercenary, while the other is his partner.
