the Jarabulus-Manbij road and two villages east of Manbij. By the evening, SDF fighters were within two kilometers south of Manbij. Furthermore, two ISIL leaders were killed by airstrikes on Jarabulus: Abu Huzaifa Alordoni and Hasan Rimo. On 7 June, the SDF captured six more villages and farms around Qara Qoqaz bridge. On 8 June, ISIL started to abandon its frontline against the Turkish-backed rebels north of Aleppo to reinforce Manbij, while the SDF captured two more villages. That morning, the rebels launched surprise simultaneous attacks from Mare' and Azaz to push back ISIL forces, which offered only token resistance. On 9 June, the SDF was trying to complete its siege on Manbij, advancing on its eastern, northern and southern side, capturing several villages in the progress. Later that day, SDF forces reached the Manbij-Aleppo road; the last major route going out of the city. According to the Syrian Observatory for Human Rights (SOHR), 49 ISIL militants and one SDF fighter were killed in the past 36 hours. The SDF announced that the emir of Manbij, Osama al-Tunisi, was among the ISIL casualties, releasing footage of his corpse. According to local activists and SDF officials, Osama had attempted to escape from the city to Al-Bab with his family and bodyguards; all of them were subsequently killed by SDF artillery bombardment. ARA News reported that Osama al-Tunisi's escape attempt and death "indicates the collapse of ISIS in the city under the ongoing operation by the western-backed SDF troops". Nevertheless, ISIL forces launched a limited counter-offensive south of Manbij on the same day, claiming to have retaken a small number of villages. Osama al-Tunisi was subsequently succeeded by Abu Khalid al-Tunisi as new Emir of Manbij. On 10 June, Manbij was completely besieged by the SDF, with all of the routes leading to Manbij cut off by SDF forces, trapping 2,000 ISIL fighters and several thousand civilians inside the city. Meanwhile, SDF forces continued to advance west of Manbij, reaching within 17 kilometers of Al-Bab by 11 June. The next day, SDF fighters advanced further, attacking the village of Um Mayyal, which served as ISIL headquarters for the countryside west of Manbij. In course of the following fierce battle, Dahham al-Hussein, ISIL emir and field commander, was killed and the village taken by the SDF. Between 12 and 13 June, an ISIL counterattack reportedly recaptured six villages around Manbij. On 13 June,
