On the BBC web site this part about today's bombings in Iraq caught my attention. Is this a freak hit, or does it mean that Bagdad is somehow mined, moled or bugged by agents of insurgent groups?

In Baghdad, Iraqi officials said Wael Rubaie, head of operations at the Ministry for National Security, and his driver were killed on their way to work.

Maj Gen Rubaie was appointed to command a special operations room recently set up to co-ordinate the fight against insurgents across all Iraqi ministries and with the US-led multi-national force.
