US Air Force under fire over Afghanistan tweet

The US Air Force drew flak Thursday after it published - then deleted - a tweet making light of a Taliban offensive that killed up to 25 Afghan forces and at least five civilians. The tweet from the official Air Force account built on an internet phenomenon in which an audio snippet with just two syllables is heard by listeners as either "Yanny" or "Laurel." The meme has prompted fierce online debate between rival camps. In an apparent attempt at humor, the Air Force linked the debate to this week's Taliban assault on Farah city in western Afghanistan, near the border with Iran.
