Pakistan's spy agency ISI provided special surveillance training to Mumbai attacks accused David Headley ahead of the 26/11 carnage. Headley who belongs to Lashkar-e-eTaiba told this to a Chicago court when he was grilled by the defence attorney Charles D Swift on the third day of the trial today of Pakistani-Canadian Tahawwur Rana. Rana is another co-accused in the 26/11 attacks. The 50-year-old Mumbai terror accused told jury during the course of questioning by Swift that the training by the Pakistan intelligence agency to Headley was provided by Major Iqbal, who was his ISI handler, on the streets and in a two-storey safe house in Lahore near the airport. Headley told the court that when he met Major Iqbal in 2006, he expressed dissatisfaction at the military and espionage training that he had received from the LeT earlier. Major Iqbal, who was identified by Headley as 'Chaudhery Khan', told him that the training received from LeT was not very good and was very elementary, so he decided to give instructions to him. The statements formed part of the testimony of Headley, who has pleaded guilty. These disclosures, which further cements India's charges that elements of ISI were involved in the 26/11, is also corroborated by information given by federal prosecutors in the documents to the court, which have been unsealed. Despite repeated questioning, Headley said that he did not know the full name of Major Iqbal, but was sure that he was from the ISI. He was introduced as Major Iqbal to him. Although Major Iqbal was never seen by Headley in military uniform, he came to meet him several times in a military jeep and his subordinates had military designations. According to the new documents, it was in February 2002, Headley began attending training camps in Pakistan for LeT.
