BRITAIN-IRAQ-SYRIA-CONFLICT

A journalist speaks to a person in the neighbouring property in London on February 26, 2015, to where Kuwaiti-born London computer programmer Mohammed Emwazi, identified by experts and the media as masked Islamic State militant "Jihadi John", is once believed to have lived. "Jihadi John", the masked Islamic State militant apparently responsible for beheading Western hostages, was named on February 26 by experts and the media. The International Centre for the Study of Radicalisation at London's King's College, a leading resource for studying foreign jihadists, said it believed the identity "to be accurate and correct".
