Gouvernement al-Hasaka
The Western al-Hasakah offensive, dubbed "Operation Commander Rûbar Qamishlo" by the Kurds, was a military operation during May 2015 in the Al-Hasakah Governorate, during the Syrian Civil War, conducted by Kurdish YPG and allied forces against the Islamic State of Iraq and the Levant. On 31 May 2015, as most of the offensive operations in the western Al-Hasakah Governorate ended, the part of the offensive in the Ras al-Ayn District expanded into the Tell Abyad region, in the northern Raqqa Governorate.
