Here are the details from USA Today.
Three Islamic State militants setting up an ambush in a bitterly contested area of northern Iraq were killed by a herd of stampeding boars, local leaders say.The ISIS members who were attacked were part of a group that were killing Iraqi villagers as they tried to leave the area because of the fighting. It is believed that they had just killed 25 innocent civilians who were trying to flee the violence.
Sheikh Anwar al-Assi, a chief of the local Ubaid tribe and supervisor of anti-ISIS forces, told The Times of London the militants were hiding on the edge of a field about 50 miles southwest of Kirkuk when the boars overwhelmed them Sunday. Five other militants were injured, al-Assi said. He said the group was poised to attack a band of local tribesmen who had fled to nearby mountains since militants seized the town of Hawija three years ago.
“It is likely their movement disturbed a herd of wild pigs, which inhabit the area as well as the nearby cornfields,” he said.
