Four charts that will tell you everything you need to know about the war with Isis, one year on

Exactly one year ago, the terror group Isis declared the establishment of an Islamic caliphate in the territory under its control in Syria and Iraq.

Since then, hundreds of thousands of people have been displaced from their homes, the Yazidi people and Christians have been persecuted for their religions, and thousands of civilians, soldiers, journalists and aid workers have been brutally murdered in Isis' consolidation of power.

In just a few short years the group has grown into one of the most successful and dangerous terror organisations ever formed, and the fight to defeat it is far from over. Below are four charts that illustrate the group's strengths to date:

Air strikes by the coalition of the willing have wiped out 10,000 Isis fighters and more than 2,000 Isis-controlled buildings since they began last August, according to US officials.

The group also actively seeks to groom and recruit impressionable young Muslim people from further afield, helped by slick propaganda videos and secure chat groups. France and the UK have respectively the 6th and 8th highest recruitment rates overall:

There are also fears that Isis' hold could spread much futher afield, with some security experts predicting the group's ideals could take root in southeast Asia.

At present there are seven other conflicts in Muslim countries where state authority is weak or non-existent, providing suitable conditions for Isis, al-Qaeda and other extremist movements to become powerful:
