Paris attacker's partner Hayat Boumeddiene on airport CCTV

CCTV at an Istanbul airport appears to show Hayat Boumeddiene, the partner of Paris supermarket attacker Amedy Coulibaly, going through passport control.

Coulibaly is thought to have killed four people in the Jewish supermarket and is also suspected of killing a French police officer.

The video, which has not been verified, purportedly shows her arriving in Istanbul on 2 January.

She is now thought to be in Islamic State-controlled Syria.
