Born Mustafa Kamel Mustafa in Egypt in 1958, Abu Hamza came to the UK to study in 1979.
He became a British citizen when he married an English woman, Valerie Fleming, but the couple later divorced.
In the early 1990s, Hamza fought alongside Bosniaks against Serbs and Croats during the Bosnian War.
On his return to the UK, he began preaching radical anti-Western sermons at Finsbury Park Mosque, in north London.
Following 9/11, Hamza's comments in support of Osama Bin Laden sparked outrage.
In 2006, he was jailed for seven years in the UK after being found guilty of 11 offences under the Terrorism Act.
Two years later Home Secretary Jacqui Smith signed an extradition order to the US, which Hamza appealed.
After another four years of legal battles, European judges ruled he would not be subject to ''ill-treatment'' in the US and could be extradited.
Hamza was finally extradited to the US in 2012, where he appeared before a New York judge and pleaded not guilty to 11 charges.
His trail opened on April 14, 2014 and concluded a month later when he was found guilty for a string of terrorist offences.
Nearly eight years since his extradition order, Hamza is finally being sentenced for his crimes in the US.
