Neither of the previous suggestions offers a good solution to this problem. I have been involved, first hand, in the negotiations that followed many cases of kidnapping. From the early cases to the most recent ones, the underlying causes and demands are quite similar. That is why, I believe that the solution to this problem lies in the ability of Sanaa to shape up. Actually, much of the money that the officials pocket could have gone to serious development projects.
Kidnapping is seen as a way to forcefully achieve the re-distribution of resources.
They want the thieves of Sanaa, who call themselves government officials, to share the bounty with them. The two sets of thieves are quite similar although the ones in Sanaa could be wearing suits and ties. The president of the republic should invite tribal elders from all over the country and discuss with them regarding their needs for development projects. Government bureaucrats have long lost touch with the actual needs of the people. Let me stress that no one condones kidnapping.
