Hundreds of thousands of Pakistanis were already fleeing the Swat Valley before the latest fighting broke out.
Sher Ali Khan, 55, is one of them. He fled his home in a village in the Swat Valley nine months ago. Sher Ali Khan now lives in a rented house in Landhi, a largely Pashtun settlement on the outskirts of Karachi.
Khan, his wife, and 13 children have been crowded into a three-room house, anxiously awaiting the day they feel it's safe enough to return home. Khan discusses his situation with reporter Jessica Partnow.
