The Obama administration has sent about 130 additional military personnel to Iraq, U.S Defense Secretary Chuck Hagel said on Tuesday, Aug 12, as Washington seeks to help Iraq contain the threat posed by hardline militants from the Islamic State. according to Reuters.

Hagel, speaking to troops in California, said the soldiers arrived in the area around Iraqi Kurdistan's capital, Arbil, earlier in the day.

A U.S. defense official, in a statement issued as Hagel was speaking, said the soldiers sent to northern Iraq would "assess the scope of the humanitarian mission and develop additional humanitarian assistance options beyond the current airdrop effort in support of displaced Iraqi civilians trapped on Sinjar Mountain by the Islamic State of Iraq and the Levant."
