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".
Setting up a state governed under strict Islamic law has long been a goal of many jihadists.
Meanwhile, Iraq's army continued an offensive to retake the northern city of Tikrit from the Isis-led rebels.
The city was seized by the insurgents on 11 June as they swept across large parts of northern-western Iraq.
In a separate development, Israel called for the creation of an independent Kurdish state in response to the gain made by the Sunni rebels in Iraq.
