Mohammed Emwazi, the Briton identified as Islamic State killer "Jihadi John," was denied entry to Tanzania in 2009 at the request of British security services, a Tanzanian police source said on Tuesday.
The source's version of events tallies with emails published by London activist group CAGE last week that they said were from Emwazi, recently named as the militant shown beheading American, British and Syrian hostages on Islamic State videos.
Security officers at Dar es Salaam airport refused to allow entry to Emwazi and two friends — another Briton and a German — because they were on an official immigration stop list, said the source who spoke to Reuters on condition of anonymity.
