A U.S. general apologized on Wednesday after the military dropped leaflets containing “insensitive” religious materials in Parwan Province on Tuesday.

“The design of the leaflets mistakenly contained an image highly offensive to both Muslims and the religion of Islam,” wrote Maj. Gen. James Linder, head of Special Operations Task Force-Afghanistan. “I sincerely apologize. We have the deepest respect for Islam and our Muslim partners worldwide.”
