Good riddance, but I don't imagine it will take long for him to be replaced.
Abu Sayyaf, key ISIS figure in Syria, killed in U.S. raid - CNN.com
U.S. Special Operations forces killed a key ISIS commander during a daring raid in eastern Syria overnight Friday to Saturday -- securing intelligence on how the terror organization operates, communicates and earns money, U.S. government officials said. The ISIS commander, Abu Sayyaf, was killed in a heavy firefight after he resisted capture in the raid at al-Omar, U.S. Secretary of Defense Ash Carter said in a statement. Sayyaf's wife, an Iraqi named Umm Sayyaf, was caught and is being held in Iraq. The ground operation was led by the Army's Delta Force, sources familiar with the mission told CNN. There were about two dozen members of Delta Force involved, sources said. They were part of a multi-branch force of about 100, the sources told CNN's Barbara Starr. Carter said he had ordered the raid at the direction of President Barack Obama. All the U.S. troops involved returned safely.
