Afghan British journalist Najibullah Quraishi has had trouble sleeping for more than two hours a stretch ever since the U.S. withdrew troops from Afghanistan in August and the Taliban came back into power. Quraishi grew up in Afghanistan under Soviet and Taliban rule, and began reporting on the Taliban before the Sept. 11, 2001, al-Qaida attacks and the onset of the U.S. Afghan war. He's currently in Kabul reporting for his upcoming PBS Frontline documentary, Taliban Takeover, (airing Oct. 12) which details life in Afghanistan now.
