Chilling new footage shows the extremist behind the Manchester synagogue terror attack just seconds before he carried out his atrocity.

Just yards from the Heaton Park Hebrew Congregation Synagogue in Crumpsall, Jihad Al-Shamie's battered hatchback can be seen driving to where worshippers are gathering at around 9.30am.

Moments earlier a man in a light brown coat and wearing a black backpack - believed to be Al-Shamie - can been seen walking furtively towards the synagogue and then away from it.

Al-Shamie had been confronted by security and left, returning shortly afterwards after fetching his car, a black Kia Picanto with a distinctive missing rear wheel trim.

Seconds after it is visible being driven past in new footage obtained by the Daily Mail, the Syrian-born 35-year-old extremist attempted to smash his way inside the building as Rabbi David Walker and courageous congregants barricaded the doors.
