A man armed with a knife has killed two people and injured a third person in northern France.

It’s reported the police have shot and killed the knifeman, after he allegedly threatened them.

The incident occurred on Thursday morning in the French suburb of Trappes, west of Paris.

Islamic State issued a statement claiming responsibility for the attack but the knifeman’s intentions are unconfirmed.

“The reason behind the attack and his profile are not known yet and are being looked into,” a source said.
