Headley, a Pakistani-American, said this while being cross-examined by defence lawyer of Tawahhur Hussain Rana, a 26/11 co-accused and a Canadian of Pakistani origin who is standing trial after being slapped with a dozen charges in connection with the Mumbai attacks in which 166 persons were killed.

"(Ilyas) Kashmiri had plan to kill CEO of Lockheed Martin to stop any further drone attacks," Headley said, adding the dreaded al Qaeda leader plotted the killing out of frustration over the attacks on the volatile Af-Pak border.

Lockheed are manufacturers of drone planes which are being used by American forces to strike targets at militant hideouts.

Headley replied in the negative when asked if he was working on a plot to kill the Lockheed Martin boss.

Headley, who has pleaded guilty in the case, testified that Kashmiri had arranged for men to carry out surveillance in the US in connection with the plot to kill the Lockheed CEO.
He also said that he tried to get a longer visa to stay in Pakistan through his school friend Aman Rashid who worked at Pakistan consulate in Chicago.

The trial has so far focussed on the testimony of Headley who has exposed the nexus between ISI and LeT in carrying out the Mumbai terror attacks.
