BBC reports:  A video has emerged in which Amedy  Coulibaly, who took hostages at a kosher supermarket in eastern Paris on Friday and who also reportedly shot dead a policewoman a day earlier, claims to be acting on behalf of Islamic State.

In the video, he pledges his allegiance to Caliph Ibrahim al-Baghdadi, the head of IS, and says he was co-ordinating his attacks with the two brothers who attacked the Charlie Hebdo offices on Wednesday.

Eleven people were killed at the magazine offices in Paris on Wednesday, with a policeman shot dead nearby. Four hostages died at the supermarket on Friday.
