WHITFIELD: Sources tell CNN that ISIS and other terror groups are developing a new bomb that's made to fit into laptops and go undetected through airport security. CNN has learned that the intelligence about these devices is the same intelligence behind a recent ban on laptops in the cabins of certain airlines arriving into the U.S. For more now I am joined by Pentagon reporter Ryan Browne. So Ryan, tell us more about this intelligence.</s>RYAN BROWNE, CNN PENTAGON REPORTER: Hi, Fredricka. This intelligence, which is being described as credible and by one official as hair-raising, was obtained from a variety of sources including human intelligence as well as intercepts. Now, one of the most concerning parts of this intelligence according to officials is that the terrorist groups may have acquired detection -- airports, they are using airports to detect this kind of scanning equipment, sophisticated scanning technology, and using that and practice and perfect their explosives. So this is something of tremendous concerns of the intelligent community. One thing in particular they note that these terror groups are sharing some information potentially. Al Qaeda in Yemen is considered particularly sophisticated in its development of explosives. They have done non-metallic liquid explosives in the past, attempting to airliners and transport planes. And even last year in Somalia we saw an explosive smuggled into a laptop into the DVD tray that was detonated. Luckily that plane was able to make a landing. But this is something that terror groups have been working in the past. So this new intelligence says they have this ability to scanner, that they're continuing to work and perfect this, help prompt this laptop ban.</s>WHITFIELD: All right, Ryan Browne in Washington, thanks so much for that update. All right, still ahead, after 19 days and more than 1,200 tips, there's a new clue in a disappearance of the disappearance of a teenage student and her teacher who is suspected of kidnapping her.
