He went on to become one of the group’s senior military leaders, commanding all ISIS fighters in Northern Syria and later taking charge of the group’s special forces. Al-Shishani has not been afraid to show his face, appearing in videos calling for a united Islamic state. The United States had offered up to $5 million reward for information about ShishanI, on a list of specially designated global terrorists. US officials are now attempting to determine whether al-Shishani, 30, was killed in the strike. There have been false reports of his death on at least three occasions. He would be one of the most senior figures killed in the coalition air campaign against the group if his death is confirmed now.
