The 11 U.S. deaths were the most in a single day
since 11 Americans were killed on Dec. 1.
On that day, 10 Marines were killed
by buried bombs as they gathered
for a promotion ceremony
in an abandoned flour mill in Fallujah,
and one soldier was killed in Ramadi.
2,194 members of the U.S. military have died since the war began,
according to an Associated Press count.
