Spillover of the Syrian Civil War
Following the outbreak of the protests of Syrian revolution during the Arab Spring in 2011 and the escalation of the ensuing conflict into a full-scale civil war by mid-2012,[1] the Syrian Civil War became a theatre of proxy warfare between various regional powers such as Turkey and Iran. Spillover of the Syrian civil war into the wider region began when the Iraqi insurgent group known as the Islamic State of Iraq (ISI) started intervening in the conflict from 2012.
In 2012, ISI began transporting its fighters, arms and supplies to Syria. In April 2013, ISI re-named itself as the "Islamic State of Iraq and Levant" (ISIL), officially announcing its expansion into Syria. Throughout 2013, ISIL fought Syrian opposition groups, gaining control of numerous villages, towns and cities in eastern and northern Syria. In late 2013, ISIL launched its Anbar campaign into regions of Western Iraq and captured Fallujah in January 2014. In June 2014, ISIL captured vaste swathes of territory during its Northern Iraq offensive, culminating in the capture of Mosul. On 29 June 2014, the group re-named itself as the "Islamic State" (IS) and declared itself as a Caliphate.[2][3][4]
