In the first look inside the terror boss’ Gitmo trial, “60 Minutes” revealed Sunday how Mohammed chills between court sessions in a special air-conditioned cell with an arrow pointing to the Muslim holy city.

He gets to the Guantanamo Bay court complex — called Camp Justice — by passing trough an outdoor corridor covered in a camouflage mesh that can stop a sniper bullet.

In the courtroom — where KSM is facing the death penalty along with four cohorts — he is given his own computer screen and translation service.
