‘We are back in America’: ISIS releases chilling new video on 9/11 anniversary where extremists threaten fresh attacks on the US

ISIS has released a chilling new video on the anniversary of 9/11 – threatening new attacks on the US.

Extremists claim they are ‘back in America’ during the ten minute video, which also warns the US to expect a repeat of the atrocity as well as ‘cars full of explosives and suicide bombers’.

The film was released as America marked 14 years to the day since two jets were flown into the World Trade Centre in New York killing nearly 3,000 people.
