It seems that Graham has very little knowledge of Yemen or the Middle East!
If a small blonde haired Caucasian female child was seen roaming the streets with locals, immediately they would be brought in for questioning. Tourism does not exist, and the laws are very strict in Yemen. There are enough European expatriates living there who would immediately bring it to the authorities attention. Being such an intense international search for Madeleine, these Yemeni Police would love the positive attention of being the ones who found Madeleine, or were the reason for the arrests of the kidnappers!! The treacherous extremely high narrow mountain passes where so many accidents occur, is the only route from Hodeida to Sanaa where the only airport exists. Yemen is full of different militants, they're known to kidnap white foreigners, mainly men, hold them for ransom and steal their 4x4's, so I doubt very much that anyone would take Madeleine to such a country. Its not a developed country and the people are very poor.
Even the ports on the Red Sea as well as the Gulf of Aden and Arabian Sea area, are all policed 24/7. Graham and all the other so called psychics and mediums should just really crawl back into the woodwork, they are just one big bunch of liars. It's about time something seriously is done to discourage and to damage the reputations of these so called soothe-sayers, aka fraudsters and money grabbers!!!!!
