(SITE Intel Group via AP) (Newser) – The Islamic State group says its spokesperson has been "martyred" in northern Syria, the AP reports. The IS-run Aamaq news agency said Tuesday that Abu Muhammed al-Adnani was "martyred while surveying the operations to repel the military campaigns against Aleppo," without providing further details. IS has released several audio files online in which Adnani, a senior leader in the group, delivers fiery sermons urging followers to carry out attacks. The extremist group has suffered a string of defeats in recent weeks, including in Syria's northern Aleppo province, where Turkish troops and allied Syrian rebels drove IS out of the border town of Jarablus last week.
