Forum:What happened to the people on the Citadel at the end?

Just for the etiquette: *SPOILERS*

So, near the end of the game, the citadel was kidnapped by the reapers, and later destroyed/Circulated through with gigantic energies. But what happened to all the people aboard? Was the defense fleet able to hold the reapers off for a time and evacuate portion of the residents? Is it possible that some people manged to leave when Shepard opened the stations arms? What do you think?
