al-wuhay >>> most worrisome, on the right, the leader, nasir al-wuhayshi, and number two, for al-qaedao osama bin laden. in the video he vows to attack the u.s. on the left a former guantanamo bay detainee. the u.s. believes the video was shot in march, warning them of the attempt to hide explosives in shoes. >> they have tried to build explosives that can get around security. we have been concerned about that for many years now. >> the chairman of the house intelligence committee telling wolf blitzer their group has gone underground in their communications even as plotting has increased. >> the more they can get away with plotting, planning, organizing, financing, all the things they would need to do to strike a western target they're going through that process, including, by the way, bringing in very sophisticated people to devise new devices that would try to get around security protocols in the u.s. and other places. >> barbara, this is pretty incredible, i guess the question is did u.s. officials know about this meeting? i mean, is there any reason they would have known about it a

the leader of this group, nasir al wuhayshi is the number two of al qaeda, appears to be emboldened asppearing with 100 fighters. in this video he's greeting people freed from a prison back in february. this is a propaganda video from the group, but also a message for the united states, we're still coming after you, he's telling america. >> this is a big in-your-face thing to the united states. but it could be a whole bunch of nothing, too, right? >> it's a propaganda video first and foremost to show supporters around the world they're still in business, still a threat inside yemen and they still intend to target the united states. they still have some ability to target the united states because they do have this very skilled bob becamer, ibrahim, somebody inhiding who is heavily protected in the group and skilled at making explosives which you can get on airlines. so a lot of concern about this. back in february the department of homeland security issued a bulletin after u.s. intelligence discovered that al siri was developing a new generation of shoe bombs. >> this gathering supposed

members of al qaeda in the arabian peninsula are shown on the tape, embracing their leader, nasir al-wuhayshi. his message is a familiar pledge to strike america. analysts are surprised that al qaeda's second most powerful leader would stage such a brazen really in a region watched by intelligence agencies and frequently hit by u.s. drone strikes. while the tape does not openly suggest an imminent attack, some of the militants' faces have been blurred. the worry is those anonymous terrorists they have some particular value in a future plot. a.q.a.p. continues to be al qaeda's most dangerous and capable franchise. the yemen-based group was behind two underwear bomb plots, a foiled attack in 2010 to bomb two cargo planes with explosives concealed in computer printers. u.s. intelligence first became aware of this new video a couple of weeks ago when it was posted on jihadi web sites, but, scott, the c.i.a. will not tell us if it knew of the meeting when it happened. >> pelley: bob orr in our washington newsroom. bob, thanks very much. today, students returned to franklin regional high school out

because the top leader, nasir al-wuhayshi, is greeting several men that al-qaeda broke out of prison are free. and he is trying to recruit them into his movement even further. so they believe it was actually in the last several weeks because of that tie to the prison breakout. >> do we know how many assets or what sort of intelligence we actually have about these groups in yemen? i mean, was the u.s. aware of this gathering? >> well, this is the absolute critical question right now. did the u.s. know about it, or is the intelligence about yemen right now so spotty that they did not know? one of the things that concerns the cia, the white house, the pentagon the most is this al-qaeda group has gone underground in its communications to a large extent. they are staying off the internet. they're staying off cell phones. they have gone back to using couriers a good deal because they are afraid of u.s. surveillance of the u.s. intercepting their communications. so this sort of going dark, if you will, is one of the big concerns that the u.s. may not know as much as it wants to about what t

this includes nasir al-wuhayshi, the leader. s leaves the question of whether or not the u.s. couldn't get a drone here in time. what do you believe this says about al-qaeda? >> well, first of all this administration tried to tell us al-qaeda was destroyed. then they said no, it is just al-qaeda core in pakistan. we have to be concerned about these affiliates. i spent time in that region, including yemen. we're seeing a coalescing of these places, not only in iraq but syria, and sooner or later if they get stronger they will be a direct threat to the united states of america. >> and how did this bubble up without our knowledge? >> well, i can't answer that question because i don't know the intelligence that has been provided to this administration, whether this has been known or not known. so we can only speculate that while this has remained classified. i don't think it is a secret to people who have the proper clearances. the question is why didn't we know, the question is what are we going to do about it? >> and what would you

america" "this is quite an extraordinary video, the leader of al qaeda in the arabian peninsula nasir al wuhayshi who is also the number 2 of al qaeda worldwide, addressing over a hundred fighters somewhere in yemen, taking a big risk in doing this." authorities believe the highly produced video is recent, with some fighters' faces blurred. there is good reason to worry too. al qaeda in the arabian peninsula -- also known as aqap -- is considered the most dangerous al qaeda affiliate. the c-i-a and the pentagon have repeatedly killed aqap leaders with drone strikes but this new video shows the group more determined than ever. we will continue with similar conditions as a touch cooler as we head into tomorrow. the sea breeze will really help regulate our temperatures. will bring us down especially along the coast. for friday look for temperatures mid-60s inland. will 60s for the coast. i think we will see a bit of a push as and into saturday and sunday. partly cloudy conditions and in a cooling trend in store with a 20 percent chance for showers. that is something we will keep a close eye on it bu
