Jihadist militant group Isis has said it is establishing a caliphate, or Islamic state, on the territories it controls in Iraq and Syria.

It also proclaimed the group's leader, Abu Bakr al-Baghdadi, as caliph and "leader for Muslims everywhere".

The group has posted footage online purportedly showing a bulldozer merging the areas it has seized, as Frank Gardner reports.
