Washington (CNN) - Additional U.S. military advisers are now on the ground in northern Iraq with the Obama administration considering a possible air evacuation of thousands of minority Yazidis under threat from Islamic State militants and trapped on Mount Sinjar.
President Barack Obama ordered nearly 130 advisers to Irbil to assess the situation, and it's now likely that a small number of them will travel to the mountain area to get a first-hand look at what might be possible.
The new group comprised of Marines and special forces adds to the hundreds of other American advisers already in the country advising Iraqi troops in their fight against Sunni militants from the Islamic State, an al Qaeda off-shoot formally known as ISIS.
