IRNA - Leader of the Iraqi National Wisdom Movement Ammar Hakim said that Iran is strategic depth of Iraq, adding its 'our duty to stand by Iran'.
Hakim made the remarks Tuesday in reaction to the US economic pressures on Iran.
Iran is under pressure, sanctions that targeted its economic and political system, he said.
Iraq should help Iran feel about sanctions, since Iran stood by Iraq in all crises.
Enjoying about 1300 km common borders with Iraq and the relations between two countries are the most reason for supporting Iran, he added.
After Washington's May 8 exit from the landmark Iran Deal formally known as the Joint Comprehensive Plan of Action (JCPOA), the US gave 90 to 180 wind-down period to other countries before it starts re-imposing oil sanctions on Tehran on November 4.
Part of the US illegitimate sanctions are to be imposed on Iran as of August 9.
