At last some insight on what is happening, thanks to FP Blog and written by an Australian:http://www.foreignpolicy.com/article...saleh?page=0,0

I don't suppose the FBI are advertising their role in this ****:
There aren't many foreigners traveling to Sanaa these days, but one group of outsiders is getting a lot of attention: an FBI forensics team, which reportedly arrived last week to investigate the attempted assassination of Yemeni President Ali Abdullah Saleh, who is now convalescing in Saudi Arabia.

Evidence from the scene indicates that the explosion may have been caused by a device that was planted inside the mosque on the presidential compound, and not by a mortar shell or rocket, as was initially reported. If true, this means that someone with close access to the president was involved, which raises the question of why members of the Yemeni regime's inner circle -- set to mark its 33rd anniversary in power next month -- now appear intent on destroying each other?
