The slain hostage-taker who killed four people in a kosher supermarket siege outside Paris last week had been on a US terror watchlist.
Amedy Coulibaly, who is suspected of taking hostages and slaying four Jewish shoppers at the Hyper Cacher supermarket to the east of the city, had been on a US terror database "for a while", a law enforcement official told CNN.
The US network said Coulibaly was on the Terrorist Identities Datamart Environment, the government's central repository that includes about one million names.

Coulibaly likely received help from others, including two brothers suspected of shooting dead 12 people at French satirical magazine Charlie Hebdo last week.
