ISIS militants from China's Muslim minority group have vowed to return home and shed rivers of blood in the terror group's first video to target the country.
The 30-minute clip was released on Monday by a branch in Iraq and features a man being executed in the presence of a child as well as claiming to show the life of Chinese terrorists based in the Middle East.
Young boys are seen practicing martial arts and assembling assault rifles in the video, which threatens bloodshed in the biggest country in the world.
The video shows groups of youngsters understood to be Uighur militants from China's Xinjiang province sitting and listening to preachers as well as issuing threats.
It was released by a division of the Islamic State in Iraq and Syria (ISIS) group in western Iraq and featuring militants from China's Uighur ethnic group, said the US-based SITE Intelligence Group, which analysed the footage.
China has for years blamed exiled Uighur 'separatists' for a series of violent attacks in its western Xinjiang region - the Uighur homeland - and warned of the potential for militants to link up with global militant groups.
The Uighur community is of Turkish origin and has regularly clashed with the government with Islamism usually at the heart of the conflict.
