So-called Islamic State (IS) has lost more than a quarter of the territory it once controlled, new data shows. Security and defence analysts IHS say the group’s control has shrunk by 28% since its height in January 2015.

In the first nine months of this year, IS’ territory fell from 78,000 sq km (30,115 sq miles) to 65,500 sq km – an area equivalent to the size of Sri Lanka – IHS analysts said.

However, IS losses have slowed in the three months to October.
