Iranian President Hassan Rouhani called on Monday for a "united front" to fight extremists in the Middle East where the Islamic State group controls territory in both Iraq and Syria.
In his address to the UN General Assembly, Rouhani also said Iran was "prepared to help bring about democracy in Syria" and in Yemen.
"I would like to invite the whole world and especially the countries in my region to form a joint comprehensive plan of action to create a united front
against extremism and violence," he said.
