>> well, as you indicated, they've already had an attack on the embassy there, and certainly there have been multiple attempts to attack the embassy in the past, some successful, some less successful. al qaeda in the arabian peninsula, the al qaeda affiliate in yemen, has tried to bring down american airlines in 2009, american cargo planes in 2010. that said, this affiliate in yemen has also been under substantial pressure. something like 37 of their top leaders and senior operatives have been killed in u.s. drone strikes in the past three years. they held significant territory in southern yemen in 2011. they were pushed out by the yemeni army with some u.s. help. and so, you know, the chatter that may have prompted this ale alert, you know, it certainly, it's prudential to close these embassy facilities, but it may all wash out.
