Obama announced on Oct. 21 that US forces would withdraw completely by year-end as scheduled under terms of a 2008 security pact, nearly nine years after the invasion that ousted Saddam Hussein.
The decision came after Washington and Baghdad failed to reach agreement to keep some troops in Iraq, despite concerns that the Iraqi forces are not ready to handle external threats.
October saw a number of major attacks including a bombing on a busy commercial street in northeastern Baghdad last Thursday that killed at least 30 and wounded scores, and a string of suicide and roadside bombings targeting police in the capital on Oct. 12 that killed at least 28.
