Born in New Mexico, Awlaki grew up in Yemen and moved to the US to study for a degree in civil engineering in Colorado and then a masters degree in education.

He preached at mosques in San Diego and Virginia where it later emerged that he had preached to three of the September 11 hijackers.

He moved to Britain between 2002 and 2004 and then returned to his native Yemen where he spent 18 months in jail.

In recent months he has been connected to Umar Farouq Abdulmutallab, the former student at University College London who tried to blow himself up on a flight to Detroit on Christmas Day using a device in his underpants.

He was also in contact with Major Nidal Hasan, who killed 13 people during a rampage at Fort Hood in Texas.

President Obama has reportedly approved his assassination, a controversial move because he is a US citizen.
