On Sept. 11, 2001, Said Noor was growing up in a mountain village in Khost, a southeastern province of Afghanistan along the border with Pakistan. He lived in an agricultural valley full of apple orchards and groves of peach trees.
On that day 20 years ago, Noor listened to BBC reports on the radio about a terrorist attack that took place halfway around the world.
"At the age of 11, I just had no idea what was going on," Noor, now 31, tells NPR.
