Three car bombs exploded Wednesday in Riyadh, a tense town north of Baghdad, killing at least five people, including three policemen.
U.S. troops found at least six bombs at different locations around Baghdad, the military said. Iraqi police discovered two more bombs in the Shiite holy city of Najaf, where turnout in the Sunday national elections is expected to be high.
In a statement, the U.S. command said the six bombs were discovered early Wednesday in widely scattered areas of the Iraqi capital.
