Tell Abyad
On 31 May, Kurdish forces seized four villages on the provincial boundary between Al-Hasakah and Raqqa. At the same time, Kurdish and FSA forces in the eastern Kobanî Canton launched a large offensive eastward towards Tell Abyad, with the YPG and FSA forces on both frontlines numbering at least 4,000. Over 35 ISIL militants were reportedly killed in the Kurdish-led offensive on 1 June. On 2 June, ISIL was reported to have dispatched 1,500 fighters to the Tell Abyad region as reinforcements, mostly to the west of Tell Abyad, to halt the Kurdish advance. ISIL was also reported to be reinforcing the approaches to Tell Abyad, including mining the roads and houses to Tell Abyad with explosives, especially in the western approaches from Kobanî.
