What the Iraqi "insurgency" is about

From the BBC report:

More than 70 people have been killed by two bombs in Baghdad, attached to two mentally disabled women and detonated remotely, says a security official. [....]

The blasts came shortly before the call to Friday prayers when many Iraqis were out shopping or meeting friends.

The first device was detonated by a female suicide bomber at around 1020 local time (0720GMT) in the popular Ghazil animal market, killing at least 46 people and injuring a further 80.

A popular spectacle for Baghdadis, the animal market only opens on Fridays and regularly draws large crowds, despite having been targeted by bombers twice in 2007.

Just 20 minutes after the first explosion, a second bomb tore through another crowded market in the Jadida area of east Baghdad, killing at least 27 people and injuring 67. [....]

It is worth reminding ourselves occasionally just who has been murdering Iraqi civilians since 2003 and why they've been doing it.
