Monday, May 2, will mark five years since al-Qaeda leader Osama bin Laden was killed by US forces in Pakistan.
The ringleader of the terror group was shot dead by US Navy seals during a raid on his compound in Abbottabad in north-eastern Pakistan in 2011 - an incident which many hoped would bring about the end of the so-called War On Terror.
US forces said that bin Laden's body was taken to Afghanistan for identification before being buried at sea, according to the Islamic tradition of burial within 24 hours after death.
The announcement of his death saw celebrations around America as US president Barack Obama claimed that "justice has been done" after the terror attacks on 11 September.
But many questioned the circumstances surrounding bin Laden's death, including the decision not to release any images of his body or DNA evidence.
Unsurprisingly, it didn't take long for conspiracy theories surrounding his death to circulate.
Here are some of the most popular, and intriguing:
Despite hopes that bin Laden’s death would be a victory in the War On Terror, the world has since seen the rise of the self-proclaimed Islamic State, which started life as an al-Qaeda franchise.
According to Farhan Zahid, a counter-terrorism expert, IS (also known as Isis, Isil or Daesh) has now over-shadowed al-Qaeda.
He said: “Isis controls a large territory in Syria and Iraq after it successfully captured Mosul, while Al-Qaeda has no territory. Isis also controls oil rigs in Iraq and Syria and has substantial financial resources.
“Because of its tremendous successes and its proclamation of Islamic Caliphate (declaring all other groups invalid and requiring members to pledge allegiance to Baghdadi as caliph) potential jihadi now tend to join Isis rather than joining Al-Qaeda.
“Finally, at least 25 Islamist groups around the world have pledged allegiance to Isis, some that were formerly associated with Al-Qaeda. Most of these Islamist groups are small, with some exceptions, including Nigerian group Boko Haram.”
