The United States has launched airstrikes at Islamic State or ISIL targets in Iraq in an expansion of its military campaign against the jihadists.
It said the strikes were in support of troops under attack and took place south-west of Baghdad.
Six ISIL vehicles were also reportedly destroyed.
The move follows US President Barack Obama speech last week in which he vowed to hunt and destroy the militants.
Until now the US has restricted itself to supporting Kurdish fighters and humanitarian missions.
It has conducted a total of 162 airstrikes across Iraq since August.
On Monday world powers meeting in Paris gave public backing to military action to fight Islamic State in Iraq.
France has already sent jets on a reconnaissance mission, a step towards becoming the first ally to join the US-led air campaign.
Several Western and Arab officials said few concrete commitments had been made but further talks would take place over the next ten days at the United Nations General Assembly.
