"It's not clear for us why such a unit, which was supposed to be trained by the Americans for years, and supposed to be one of the best units in the army, would withdraw from Ramadi in such a way," he said, adding that "this is not the army that we are willing to see or we are expecting to see."
US Defense Secretary Ashton Carter said earlier that ISIL captured Ramadi because the Iraqi military refused to fight. According to the Pentagon, Iraqi forces greatly outnumbered the enemy, yet fled the battle.
The militants took control of Ramadi, located some 80 miles west of Baghdad, on May 17 after several days of intense fighting.
Iraqi forces and Kurdish militias are attempting to counter the advance of ISIL on the ground, while a US-led international coalition conducts airstrikes on ISIL positions. The coalition is also responsible for the training and equipping of the Iraqi and Kurdish security forces.
