Roads to Iraq picks up a report from Barakish:
Last information revealed that suicide bomber (you can see his decapitate head here), is stepped out a black car with tinted car-windows five minutes before he committed the suicide attempt (I don’t think Al-Qaeda members are driving in the cities with tinted car-windows, P.S. in Yemen and most Arab countries, you need a permission to drive such cars).
There are some interesting analysis says that this is an attempt planned by the Yemeni government to force the countries who promised to donate for the development of Yemen (and broke their promises).
One deduction we can make about the plot against the UK ambassador is that it was hatched by the same planner who previously attacked South Korean investigators in March 2009, also by bouncing an explosives laden youth off of a moving car. In that attack as well, no one was killed but the two suicide bombers.
The other relevant fact of the earlier attack is that al Qaeda admitted their operatives received inside information from the security forces. Even the Yemeni Parliament said the attack was proof the security forces were compromised. If we assume the same planner, we can then reasonably assume the same connections into the Yemeni intelligence and security forces still exist. The yet unconfirmed report that the youth arrived in a black car five minutes before the ambassador passed may indicate that the attacker knew the route and was laying in wait, as in the earlier instance. In the current case, the question remains, did Saleh call in a favor or did al Qaeda?
