Isis video 'shows al-Baghdadi alive' after death rumours

The Islamist militant group Isis has released a video apparently showing its leader Abu Bakr al-Baghdadi giving a sermon at a mosque in Mosul, northern Iraq.

In his address to the congregation, Baghdadi preaches about the importance of Ramadan and jihad.

It is thought to be the first video of the Islamist leader - and has surfaced some 24 hours after rumours he had been injured, or even killed in an attack.

Baghdad correspondent Paul Adams explained why the man in the video was thought to be Baghdadi.
