Bulgaria's parliament has approved a plan to withdraw all Bulgarian troops from Iraq by the end of the year.

The decision in Sofia Thursday finalizes a March proposal by the government of Prime Minister Simeon Saxe-Coburg-Gotha to withdraw the 450-soldiers by December.

It also comes one month before voters, many opposed to the troop deployment, elect a new parliament. 

Opposition Socialists, who have been ahead in opinion polls, oppose Bulgaria's continued involvement in Iraq.

Nine Bulgarian soldiers have been killed in the war-torn country, including one by U.S. troops in a friendly fire incident.
