It looks like there has been a murder-suicide bombing in Marakesh in Morocco. There have been stirrings of trouble in Morocco, and this murder-suicide bombing (a terrorist attack) looks like being the first warning shot of what is to come. You can read more information about the bombing at the BBC news site here.
Morocco is one of the countries where there have been protests, but for the most part there has not been the bloody crackdown that has been seen in Syria and Libya. This is not good news because it shows a new escalation in the unrest in the Middle East.
It is difficult to speculate on who is behind the attack, but I would look first to the Salafists and AQ. They seem to be stepping up their activity in response to weak leadership in the USA.
