More than 20 jihadist groups have pledged their allegiance to the Islamic State movement and 10 others have voiced their support for the extremist organisation, according to US monitoring body IntelCenter.
A list published by the centre which monitors extremist groups shows these 31 organisations are dotted across the world in an arc going from Algeria in the west to Indonesia in the east.
Abu Bakr al-Baghdadi, the head of IS which controls swathes of Syria and Iraq, proclaimed the establishment of an "Islamic caliphate" at the end of June last year after his fighters captured the Iraqi city of Mosul, asking all Muslims around the world to swear allegiance to him.
Ten other groups have voiced their support for IS, without pledging formal allegiance, IntelCenter said.
