US-backed Syrian fighters seize haul of IS documents

US-backed Syrian fighters battling the Islamic State group have snatched thousands of documents, cellphones and other digital devices from the jihadists, a Pentagon official said Wednesday.

The seizure came as an anti-IS force comprising Kurdish and Syrian Arab fighters hones in on the northern city of Manbij, an important waypoint between the Turkish border and Raqa, the jihadists’ de facto capital.

Colonel Chris Garver, a spokesman for the US-led anti-IS campaign, said Syrian Arab fighters were establishing “footholds” on the southern and western edges of Manbij, and had seized entrances to an intricate jihadist tunnel complex.

They “also seized more than 10,000 documents from the outlying edges, including textbooks, propaganda posters, cellphones, laptops, maps and digital storage devices,” Garver told reporters.

“Exploitation of this information is ongoing to better understand Daesh networks and techniques, including the systems to manage the flow of foreign fighters into Syria and Iraq,” he added, using an Arabic abbreviation for the IS group.

Pentagon officials often highlight the value of such information, leading to new targets and helping them understand the IS network.

Separately, in the southeastern corner of Syria, a group of US-trained rebels called the New Syrian Army was Wednesday battling for control of territory near the Albu Kamal border crossing with Iraq.

Their goal was to cut IS military supply lines in the Euphrates Valley between Syria and Iraq.

The Syrian Observatory for Human Rights said the rebels had seized the small Al-Hamdan airbase nearby, but IS jihadists recaptured it by Wednesday afternoon and had been forced to retreat.

Garver did not provide additional details on the ongoing fight but stressed the value of the border crossing.

“That fight is important because that’s going to help slow down the flow of foreign fighters … from Iraq to Syria and back,” he said.

The Pentagon claims numbers of foreign fighters coming into Iraq and Syria have dropped from about 2,000 a month last year to as few as 200 a month this year.

“You don’t see the massive amounts of movement. It’s certainly been whittled down in its size,” Garver said.

IS seized the Albu Kamal crossing in mid-2014, when it overran swaths of territory on both sides of the border and declared a self-styled “caliphate.”

Over in Iraq, Garver said attention is now shifting from Fallujah, which Iraqi security forces last week recaptured from the IS group, to the jihadists’ main stronghold in the country, Mosul.

Coalition air strikes destroyed IS’s “self-proclaimed ministry of oil headquarters” in Mosul and continue to hit targets in the city, Garver said.
