Tanzim Hurras al-Din, sometimes referred to as Al-Qaeda in Syria, was a Salafi Jihadist organization that fought in the Syrian civil war. The group's former head, Abu Humam al-Shami, was the general military commander of the defunct Al-Nusra Front, and had fought for Al-Qaeda during the Third Afghan Civil War and the Iraqi insurgency. Hurras al-Din was established by the leaders of the AQ-affiliated Khorasan group and Al-Qaeda loyalists of Al-Nusra Front who opposed Al-Nusra's dissolution and merger with other Islamic groups to form Tahrir al-Sham. Al-Shami announced the formation of Hurras al-Din on 27 February 2018.
