The remarks of Ali Akbar Velayati, Khamenei's adviser for international affairs, echo those made by the ayatollah earlier this month.
The #IranDeal text approved or not, we won’t stop supporting the oppressed nation in Palestine, Yemen, Syria, Bahrain and Lebanon

Ali Akbar Velayati also believes that Iran's assistance to Iraq has been instrumental in containing Islamic State and preventing militants from marching on Baghdad, the Fars news agency reported.
The brutal Sunni group shocked the world in June 2014 after it seized a third of Iraq's territory, including the second largest city in the country. Islamic State's successes in Iraq and Syria fueled fears that militants would try to capture Baghdad.
Iran was one of the first countries to come to Iraq's assistance.
