U.S. Marine Col. Charles Gurganus said gunfire broke out on the northeast corner of the plaza and several people were wounded before Marines spotted two gunmen. When the gunmen tried to attack the Marines, the troops shot and killed one of them, he said, adding that he did not know what happened to the other man.
Asked how he knew the man killed was a gunman, Gurganus said: "He had a gun, and he was shooting at Marines. That's what I call a gunman."
