“We don’t want such a coordination as their main objective is to stop Iran’s presence in the region,” Khamenei said in a transcript from a speech to university students.

Iran and Russia support Syrian President Bashar al-Assad’s fight against armed rebels and jihadists, including those of the Islamic State (IS) group.

Tehran rejects any coordination with the US-led coalition that is also bombing the jihadists in Syria and Iraq.

Khamenei repeated demands for the US to stop interfering in the region and said Washington was still acting aggressively despite last year’s nuclear accord with world powers to end Iran’s isolation.
