Iran Speaker hit out at Washington Wednesday, accusing it of disrupting implementation of last year's landmark nuclear deal and failing in the fight against the Takfiri group, ISIL.

"With great sadness, parliament... warns the US administration, House of Representatives and Senate that the efforts to undermine the nuclear agreement have reached a point that leaves no option for Iran but confrontation," he said.

Larjiani said the West had failed to give Iran sufficient recognition for its contribution to the fight against ISIL and hit out at the United Nations for continuing sanctions against its foreign operations commander.

The Iranian Speaker said Western governments should be "thankful to Iran and (its elite Revolutionary Guard foreign operations unit) the Quds Force who have helped Iraq against the bestial terrorists" of ISIL.

"You, who neither have the courage to confront Daesh (ISIL), nor know how to fight it, as they carry out bloody attacks in three European countries... how dare you call the admirable Quds Force's fight a violation?" he asked.
