Jesus Christ. The insurgents are getting even more sophisticated. What a mess:
Four U.S. soldiers were among at least 15 people killed in a bloody day of suicide car bombings in and around Baghdad on Monday as a major offensive against Sunni Arab insurgents took place near Iraq's border with Syria.
The four soldiers from Task Force Baghdad were killed when a car bomber attacked their checkpoint on a road south of Baghdad, the military said in a statement.
The attack echoed a similar attack a week ago when four U.S. soldiers were killed in Yusufiya, just south of Baghdad.
