The first military commission trial of the Obama administration is set to get under way here at the sweltering US military base on the island of Cuba.
Along with 37 other journalists, I've been flown here by the Pentagon to observe and report on this military trial. It is my seventh time here. The mood is even more serious and uptight than normal: five colleagues were banned from Guantanamo earlier this year for publishing the name of an interrogator.
Their media organisations fought back and they were re-admitted. We've all been given new rules that expand the already strict procedures we must follow.
It's almost impossible to take a picture outside two or three locations and all television footage is examined frame-by-frame by a censor for "security" reasons. Agreeing to these rules is a condition for being allowed here.
