US military advisers have begun arriving in Baghdad to help the Iraqi army in fighting against the Sunni insurgency.

A total of 300 US military advisers and troops are expected to be stationed in Baghdad. Initially they will not be involved directly in the fighting, but will carry out surveillance and plan the combat operations, Al-Jazeera reports.

A further 250-300 troops have already been deployed to provide security for the US embassy in Baghdad.

The jihadist Islamic State in Iraq and the Levant (ISIS) has been advancing southward and capturing key cities in the past weeks, including Mosul, the second largest in the country. United Nations estimates revealed that over 1,000 people, including many civilians had been killed this month alone.

There is no set deadline for the US mission, which is considered to be a “short-term” one.
