Not much suprises me any more, but sometimes you just despair.

A US military official has said children have been used in a bomb attack in Iraq, raising fears that insurgents are using a new tactic.

Gen Michael Barbero said a vehicle stopped at a checkpoint was waved through because two children were seen in the back, but was then detonated. Militants were changing tactics in response to tighter security, he said.
Five people including the children died and another seven were injured in the attack, in Baghdad on Sunday.
There were two adults in the car.  They parked it near a market, abandoned it with the children inside and apparently detonated it.
