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.

It includes another quote from the terrorist saying: 'For as long as I can remember, I have felt tormented and at war, and have felt hatred and animosity for Americans.'

It comes just a day after a recording emerged of the leader of Al-Qaeda delivering a sinister message to young Muslim men in the United States and other Western countries, encouraging them to carry out attacks in their home countries.

Terror leader Ayman al-Zawahiri made the call to arms in an audio recording that was posted online on Sunday.
