The al-Nusra Front is proving to be "the most aggressive and successful arm of the rebel force" in Syria, but they are also Islamist extremists and express hostility toward America and Israel. Al-Nusra has claimed an ultimate goal of instituting sharia law following any government overthrow, which should concern allied Syrians and America.
The group was designated by the United States as a terrorist organisation in December 2012.
The al-Nusra Front released a video showing an ambush in which its fighters simultaneously detonated 50 explosive devices on a Syrian military convoy in the Eastern Ghotah area of Damascus, Syria.
