Excerpt:
Scotland Yard is investigating a video apparently made by Somali militant group al-Shabab after British Muslims who have spoken out against the killing of Lee Rigby in Woolwich were named as targets.
The hour-long film, narrated by an unidentified man with a British accent, reportedly praises acts of Islamist terrorism and starts by hailing the killing of Fusilier Rigby.
The video singles out British Muslim commentator Mohammed Ansar as one of those who "distanced themselves" from those who carried out the attacks and as having "mutilated the teachings of Islam", according to reports.
