The use of roadside bombs in Iraq has been rising since January, when it
hit a low of 114. By April it had risen to over 250. The previous high had been
432 in May, 2007, as the successful surge offensive was getting underway. The
big difference now is the majority of the bombs are being placed by Shia
terrorists. Most of these men belong to pro-Iranian groups, that want to turn
Iraq into a religious dictatorship. Many
of these bombs are built noticeably different from the ones employed by Sunni
Arab terrorists over the past four years. The Shia militias received bomb
making training either in Iran, or from Iran bomb specialists brought into Iraq
to conduct courses. The most obvious example of this is the shaped charge, self-forging
projectile bomb, an armor piercing device that requires a machined component.
This often comes from Iran. As with the
Sunni Arab bombs, most of the Shia ones are detected, or shut down with
electronic devices before they can detonate.
One similarity is that most of the bomb casualties are Iraqis, both security
forces (army, police) or civilians who had the misfortune to be nearby when the
thing went off.
