US Edition Osama bin Laden may have been killed in 2011, but al-Qaeda - the umbrella Islamist terror group he founded - endures in many forms around the world.
Recent events in Syria and Iraq demonstrate the continued threat its offshoot group Isis - the Islamic State of Iraq and al-Sham (Syria) - represents to the region and broader world.
Groups including Boko Haram in Nigeria, al-Shabaab in Somalia and al-Qaeda in the Arabian Peninsula in Yemen have varying ties to bin Laden's organisation, which is itself now run by Ayman al-Zawahiri.
In addition the terror wrought by "loan wolves" such as the murderers of Drummer Lee Rigby in London in 2013 are traceable to al-Qaeda's influence.
The above map shows where in the world these organisations currently hold sway - as well as where they are gaining or losing influence - and gives details of their affiliations.
