Exclusive: ISIS pours massive force into Deir ez-Zour

DEBKAfile was founded by a team of journalists in June 2000 as an independent Internet Web site, providing an intelligence and security news service. January 27, 2017, 9:49 PM (IDT)

The Islamic State has gathered thousands of fighters from Iraq and across Syria to bolster a major offensive for the control of the strategic Syrian town of Deir Eez-Zour, which commands Syria’s eastern borders with Iraq and Jordan and the approaches to the Euphrates Valley. This is reported by DEBKAfile’s exclusive counterterrorism sources. They bring with them armored vehicles including tanks and long-range artillery batteries.
Although ISIS holds part of the town, Syrian government and allied forces are holding out under siege in some positions and at an important air base. Our sources report that ISIS has timed its offensive for the heavy winter conditions prevailing over the Middle East from Friday, which are keeping the US, Russian and Syrian air force planes grounded after they pounded ISIS targets during last week. 

Our unique angle on these subjects – and strong intelligence dimension – has earned DEBKAfile a global reputation and a steady readership – which skyrockets in times of crisis.
