A revealing new documentary screening next month will show the secret lives of jihadists at an Al-Qaeda training camp in the Saudi Arabian desert.
The term 'Jihadism' is used to describe Islamist militant movements that are perceived to be threatening to the West.
Path of Blood, a documentary by BAFTA Award-winning filmmaker Jonathan Hacker, who produced The Hurt Locker, features amateur videos shot by jihadists training in the vast Saudi Arabian desert.
The footage was captured by Saudi Arabian security forces, The Daily Mail reports.

- Al-Qaeda leader calls for attacks on 'every Jew'
The videos appear to show the terrorists-in-training having fun participating in a wheelbarrow race at the secret boot camp on the Arabian Peninsula.
"It is the story of Muslim terrorists targeting Muslim civilians, who are brought to justice by Muslim security agents - a stark reminder that all who are touched by terrorism are victimised by it," says Trinity Film, the group that backed the documentary.
In the film's trailer, it says Al-Qaeda has been targeting Saudi Arabia since 2003, and during that time "hundreds of their videos were captured by special forces". It is footage the terrorists "wanted to keep secret," the trailer says.
"Delete it," says one jihadist in the video. "You could see my underwear."
Osama bin Laden, the founder of Al-Qaeda, the organisation responsible for the September 11 attacks on the United States and many other mass-casualty attacks worldwide, had a plan to seize the Land of the Two Holy Mosques, the trailer says.
The Kingdom of Saudi Arabia is often referred to as the Land of the Two Holy Mosques in reference to the Al-Masjid al-Haram mosque ('Great Mosque of Mecca') in Mecca and the Al-Masjid an-Nabawi mosque in Medina, considered the two holiest places in Islam.
Bin Laden hoped to establish a worldwide Muslim empire, the documentary claims.
"The best thing about a car bomb is the martyr doesn't feel anything. It just goes up," says a jihadist in the trailer.
The documentary has been dubbed "eye-opening".
