The US court in its 12-count indictment against terror suspects Tahawwur Hussain Rana and David Coleman Headley gave extensive details of the planning of the Mumbai attack.
The chargesheet pointed out how Lashkar-e-Toiba leaders guided their men during the four-day siege beginning Nov 26, 2008.
According to the chargesheet, during the attacks, the gunmen were in telephonic contact with three LeT leaders - identified as Members A, B and C -- all of whom were located in Pakistan.
They were advised to kill hostages and throw grenades.
"LeT Member A also sought to arrange the release of a hostage in exchange for the release of a captured attacker," the chargesheet said.
The terrorists were given training in various skills including combat tactics, room entry, hostage rescue, nautical training and swimming.
