jessica buchanan and paul tisted, a danish man, were rescued. is this the way to deal with the growing problem of kidnapping in the horn of africa? frank, what do we know about what happened last night? >> this was a very during nighttime raid that took place overnight. u.s. special forces, navy seals, the same group that took part in the killing of osama bin laden in may of last year. we're told they parachuted in to a point near to the camp where these amendments were keeping these two aid workers -- where these kidnappers were keeping these two aid workers. because one of them is a u.s. citizen, the u.s. mustered the resources, exchanged fire with the bandits. they had been chewing the narcotic leaf in the previous evening and nine of the bandits killed. both of the aid workers were rescued unharmed and taken to nearby djibouti. it has been called a success because both hostages were rescued unharmed. we're told at least eight pilots were killed. that still leaves over 150 hostages, mostly sailors, held by somali pirates. there ransoms are we

we understand that jessica buchanan and paul tisted are safe and are on their way into djibouti. that is where americans have a base. >> we are used to people being picked up at sea. that is common practice now. what does this tell us about the way in which pilots are prepared to operate now? >> they were picked up in central somalia in broad daylight, the two aid workers. the security team actually picked off the gang that held them at gunpoint. they were betrayed by their own security. haveof the attacks at seat become more difficult because there are more armed guards protecting those vessels. so there has been a spy in the number of kidnappings and abductions in somalia and across the border in kenya. gangs are looking to try to take people hostage on land instead of at asea. -- at sea. nevertheless, it is the same people. then they are held on the coast and there's usually a very long wait for a large ransom. in this case they were taken back in october. so they are very lucky to have gotten out after a relatively short time in captivity. >> that's true. thank you very much.
