Aafia Siddiqui's "missing years"

Aafia Siddiqui, the Pakistani scientist found guilty of attempting to kill American servicemen by a US court, "disappeared" from Karachi in March 2003.

Her family says she was held at the US military's Bagram airbase in Afghanistan.

But her first husband says she spent five years on the run with her children, before being arrested in 2008 with her adopted son in Afghanistan.

Al Jazeera's David Chater reports on Siddiqui's "missing years".
