By "directly affected" I meant "had anything happen to them specifically as a result of the incident, other than having general feelings about the fact that it happened in their country."

An acquaintance of mine -- one whom I didn't much care for -- turned out later to have been in the city at the time, close enough to see the towers fall but not close enough to be within range of debris or anything. I think that was the closest anyone I knew came to being affected at all, except to the extent that everyone in the country was.
