Scores of American officials fled the hotel in pajamas and shorts after the 6:10 a.m. assault, which apparently used a makeshift rocket battery on a timer that had been wheeled into a nearby park.
More details in this story.
Somebody went to an awful lot of work to make sure the instigators did not have to be on the scene and in danger when the rockets were fired. Not the same mindset at all as that of suicide bombers, and implies we are dealing with a different group than the recent car bombs, organized by people who are not eager to die.
