Fourteen civilians were killed and six others wounded in two suicide car bombings near a U.S. military checkpoint outside Baghdad international airport on Sunday, the U.S. military said.

"Terrorists killed 14 Iraqi citizens and injured at least six when two vehicles packed with explosives detonated near a Victory Base checkpoint in west Baghdad May 14," the military said in a statement.

It said the attack targeted Iraqi civilians rather than the U.S. compound.

"This was not an attack on the compound. Instead, it targeted Iraqis congregated in a parking lot," the statement said.

The incident is under investigation by Iraqi authorities, it said.
