Headley spills the beans on his ISI handlers

Abdur Rehman Hashim Syed, aka 'Pasha'

David Coleman Headley, the Pakistani-American and former DEA informant, is providing entertaining testimony in the Chicago trial of Tahawwur Hussain Rana, accused of providing support to the 2008 Mumbai attacks. Headley is going full tilt to implicate Pakistan's ISI intelligence service in the attacks, yesterday alleging that he had done most of his reconnaissance in coordination with a retired Pakistani military officer called Abdur Rehman Hashim Syed, also known as 'Pasha'. Rehman has also been indicted for conspiracy to murder by the same court and for providing material help to terrorists, although he is still at large in Pakistan. The indictment can be found here.
You can find Rana's indictment - which also indicts the notorious al-Qaeda and Lashkar-e-Toiba leader Ilyas Kashmiri - here.
All the exhibits in the trial, including some useful photos and maps, as well as emails between Headley and Rana, can be found here.
Headley himself has already pleaded guilty to 12 terrorism charges connected to Mumbai and an aborted plan to attack the Danish newspaper Morgenavisen Jyllands-Posten. He was able to negotiate a plea bargain deal that means he will be spared the death penalty so long as he continues to cooperate with law enforcement agencies. The plea agreement itself can be found here.
