The U.S.-led anti-Islamic State coalition has conducted a series of airstrikes aimed at preventing a convoy of vehicles from Syria from transporting fighters to the border with Iraq.
The convoy was arranged in a deal by Lebanon's Hezbollah group, the military said Wednesday.
"The Coalition was not a party to any agreement between the Lebanese Hezbollah, the Syrian regime and ISIS," a statement issued by the coalition said.
The statement said only "individual vehicles and fighters that were clearly identified as ISIS" were struck, along with sections of road to block the convoy's movement.
"In accordance with the law of armed conflict, the Coalition cratered the road heading east between Hamaymah and Abul Kamal to prevent the further transport of ISIS fighters to the border area of our Iraqi partners," the statement said.
"To prevent the convoy from moving further east, we cratered the road and destroyed a small bridge," said U.S. military spokesman Col. Ryan Dillon, in an email to the Washington Examiner.
About 300 fighters and almost as many family members are on buses being evacuated under the controversial deal, which was brokered to end the presence of ISIS along the Lebanon-Syria border.
"ISIS is a global threat; relocating terrorists from one place to another for someone else to deal with, is not a lasting solution," Dillon said. "This is further evidence of why Coalition military action to defeat ISIS in Syria is necessary.
The U.S.-led coalition says it will continue to monitor the movement of the convoy and "will take action against ISIS whenever and wherever we are able to," in accordance with the law of armed conflict.
