After Kurdish fighters backed by American air power drove the Islamic State militant group from the key Syrian border town of Kobane in January, it lay in ruins. Hundreds of airstrikes by the U.S.-led military coalition fighting the militants had rained down in previous months, and ground fighting had also taken a heavy toll.

A new report released Wednesday by the non-governmental organization Handicap International details what that means nearly six months later. Kobane’s people must contend with a horrific array of unexploded ordnance, ranging from bombs and mortars to corpses that have been booby-trapped with improvised explosive devices, the organization found.

“The unexploded devices and booby traps pose a daily threat to the people who fled Kobane and are now trying to return home,” said Frédéric Maio of Handicap International. “This explosive pollution will make it impossible for people to reconstruct their lives, and blocks access to several areas. It also prevents humanitarian organizations from operating safely and providing the necessary support to this vulnerable population.”

The center of Kobane was hit the hardest, and remains the most contaminated by ordnance. Parts of southern and northern Kobane also were devastated, and remain littered with explosives, Handicap International found. They released this chart to illustrate the problem:

The town had about 60,000 inhabitants before the fighting began, and most evacuated north into Turkey. Weapons found in Kobane by Handicap International include aerial bombs, cluster munitions, grenades, mortars, rockets and anti-aircraft weapons known as man-portable air defense systems (MANPADS).

The booby-traps pose a significant threat, the organization found.

“They were found among the rubble of homes — attached to furniture, doors, and windows — in vehicles like cars or tractors, hidden in olive groves, water supply systems, cultivable areas, and beyond,” Handicap’s report said. “They prevent the safe return of inhabitants and create an atmosphere of terror by preventing any movement or normal, everyday life activities.”

Perhaps the most grisly discovery was the use of corpses booby-trapped with explosives. Handicap said the headless bodies were filled with more than 40 pounds of explosives and steel ball bearings, and rigged to detonate if touched.

“Previous attempts to recover such bodies ended in tragic accidents,” the report said. “Since then, the bodies have remained where they are, and continue to decompose while awaiting intervention by deminers trained in booby trap clearance.”

Handicap released the following photographs to The Post to illustrate its findings:
