Jihadi John identified: The life of Mohammed Emwazi before he joined Islamic State
Here is a timeline of events in Mohammed Emwazi's life
A human rights group has released an extensive report on its contact with Mohammed Emwazi - the man reports have named as Islamic State militant Jihadi John.
Cage, which deals with people who believe they have been mistreated at the hands of British authorities in anti-terror operations, claims it first came into contact with Emwazi in 2009 after he was contacted by MI5 on a safari holiday to Tanzania.
The group claim Emwazi's family was told he had travelled to Syria in 2013.
Here is a timeline of events in Emwazi's life as reported by Cage:
1988 - Emwazi is born in Kuwait and moves to the UK at the age of six.
2009 - He completes a degree in computing from the University of Westminster. He arranges to marry a woman in Kuwait.
August 2009 - Emwazi travels to Tanzania with two friends for a Safari holiday. Upon arrival, all three are stopped at the airport in Dar-es-Salaam by border officials and refused entry. The men spend the night in a police station near to the airport in Dar-es-Salaam.
They are put on a plane to Schipol, Amsterdam, where they are questioned by a number of men, reportedly including an MI5 officer, who accuse him of attempting to travel to Somalia. Emwazi claims MI5 then tried to recruit him.
The men are released and allowed to return to Dover, where they are questioned again by anti-terror officers.
Emwazi claims the police spoke to his fiancee in Kuwait, ultimately leading her to call off the arranged marriage.
