evidence: One of Abu Bakr al-Baghdadi’s closest collaborators, a relative through marriage, provided key information about the ISIS leader that helped lead to his capture, a senior Iraqi government official told CNN. [...] Fadhil Abu-Ragheef, an Iraqi security expert, told CNN that Sajet gave information to the Iraqis, who shared it with the US and ultimately led them to Baghdadi’s compound in Syria’s northwestern Idlib province. Sajet told Al Arabiya that another ISIS member told him he had secured a location in Idlib for Baghdadi.
