(CNN) The latest ISIS-appointed governor of Mosul was killed in coalition airstrikes on Thursday, according to Iraqi police.

Hassan Saeed Al-Jabouri, also known as Abu Taluut, was killed 18 miles south of Mosul in the village of Qayyara, according to Maj. Gen. Watheq Al-Hamdani, a senior regional Iraqi police commander who is leading the government's efforts to retake Mosul from ISIS.

Jabouri is the second ISIS-appointed governor of Mosul killed by airstrikes and had been in office for less than 25 days.

Earlier this month, U.S. airstrikes killed one of his predecessors, Radwan Taleb Al-Hamdouni, according to U.S. security officials.

Mosul is a key stronghold for ISIS fighters and was taken from Iraqi forces earlier this year. The Pentagon said that it has a strategy to retake the city beginning in January.
