According to Defense Department officials, the bombing killed Mahir al-Agal, the leader of the ISIL in Syria, which was considered one of the most prominent leaders of the organization.

The Pentagon said al-Agal was shot on a motorcycle in the Jandaris area northwest of Aleppo, and one of his close associates was seriously injured.

Meanwhile, the Syrian Observatory for Human Rights said the ISIL leader was traveling under a fake identity in areas controlled by the Jaish al-Sharqiyah group near Turkey around the city of Afrin.
