Mumbai, July 24 - A Special Court conducting the 26/11 Mumbai terror attacks case Friday allowed summons to be issued to two US Federal Bureau of Investigation (FBI) officials and three US nationals to depose in the trial.

Special Judge M.L. Tahilyani gave his ruling on an application by Special Public Prosecutor Ujjwal Nikam seeking the court's permission to summon the FBI officials who had assisted the Mumbai Police in the terror attacks probe.

Nikam had argued that the evidence of the FBI officials could reveal the conspiracy behind the attacks and prove crucial in nailing Mohammed Ajmal Amir alias Kasab, the lone surviving terrorist who along with nine accomplices had created mayhem in Mumbai.

He informed the Special Court that he would submit the names of the FBI officials next week and other details of when they would come to depose.
