Bombing Kills 4 Iraqi Civilians in Baghdad

BAGHDAD, Iraq (AP) - A car bomb exploded near a two-car convoy carrying foreigners through central Baghdad on Saturday, killing four Iraqi civilians, police said.

Did the car just explode on its own?

There is no mention that Muslim terrorists murdered 4 innocent Iraqi civilians. That appears too much for the AP reporter, HAMID AHMED, to report.
