A terrorist bomb-making video watched by Salman Abedi before he blew himself up at a Manchester pop concert is still being shared on YouTube, the US Senate has heard. A senate committee questioned how the video was getting round the web giant’s safeguards designed to stop extremists posting propaganda and terrorist content. Sen John Thune, chairman of the commerce committee, said: “According to the Counter Extremism Project, one single bomb making video used to instruct the Manchester suicide bomber has been uploaded to YouTube and removed 11 times but continues to resurface as recently as this month. How is it possible for that to happen?” The bomb-making tutorial features a balaclava-wearing Islamic State group fighter standing in a kitchen and explaining how to build a bomb with easy to obtain ingredients.
