A US citizen, who joined the Al Qaeda-affiliated Islamic State of Iraq and al-Shams (ISIS) in Syria, has sent a video message to the West expressing his desire to wage total war against the "infidels" and impose Islamic rule over the entire world. 

The video features "the American Abu-Dj'ana," brandishing a Kalashnikov assault rifle and a bayonet, who says the following:

"This is a message to people in the West from the Mujahideen (lit. "holy warriors") in Syria. We came here from different countries to protect this land, this Islamic land; to spread the Law of Allah on earth; and to dedicate our lives for Jihad in order so that we can get to heaven."

"We are coming to kill all the infidels in the West and beyond to spread Allah's law (Sharia) and the book of Allah (Koran) and to raise them to the highest level," he continues. 

"We came to kill anyone that stands in our way. The flag that says that 'there is no God but Allah' will be raised over Parliament Buildings and in capital cities around the world [. . .] with these simple weapons we will liberate this country and this people and  bring Islamic law to control all the world - Europe, U.S., Australia, New Zealand, Asia and Africa. "

Western states have grown increasingly worried over the influx of foreign fighters - many of them from Europe and North America - to take part in the Syrian civil war. Although many of them are fighting with non-Al Qaeda-aligned groups, a growing number are joining the ranks of its affiliates such as ISIS and the Nusra Front. Western intelligence officials worry about "the day after", when those battle-hardened Islamists return to their home countries, posing a real security threat there.

Videos like these, showcasing Western-born Islamists fighting for Al Qaeda in Syria, are still rare, but have become increasingly common as ISIS and the Nusra Front seek to bolster their presence and encourage new recruits, in the face of mounting losses both against government forces and Kurdish militias in northern Syria.

Over 11,000 children alone have been killed in the bloody conflict, which has raged in the region since 2011. Foreign nationals have been pouring into Syria to engage in the Civil War, which has mushroomed from a national conflict into an all-out holy war between various Islamic factions. Even among the rebels, there has been a marked lack of unity, with Al Qaeda groups like this one dividing the rebel camps, as some rebels focus more on domestic issues and less on a global Jihad campaign.
