'Exactly what country is it that Iraqis who rose up to defend their homes against ISIS return to? Shameful US FP, dictated by petrodollars,' Zarif said in a Twitter message in reaction to Tillerson recent allegations on Iraqi popular forces.
During his tour to Saudi Arabia, Tillerson on Sunday urged Iraqi popular forces to 'go home' or leave the country.
Tillerson is in Saudi Arabia on the first leg of his one-week Middle East and European tour which will later take him to Qatar, India, Pakistan and the Switzerland.
