Iran's Vice President Eshaq Jahangiri says gradual reform within the framework of the law is the way to improve the situation in the country amid anti-establishment protests.
Turkey on Tuesday said it was "concerned" by days-long protests that have engulfed neighbouring Iran, warning against any escalation in the unrest, AFP reports.
"Turkey is concerned by news the protests in Iran... are spreading, causing casualties and also the fact that some public buildings were damaged," the foreign ministry said in a statement, adding "common sense should prevail to prevent any escalation."
Turkey -- which was hit by protests against President Recep Tayyip Erdogan (then premier) in 2013 -- said it "attaches the utmost importance to the maintenance of peace and stability in friendly and brotherly Iran."
The ministry said Rouhani's statements warning against violation of laws and damage of public property should be adhered to.
"We believe that violence and provocations should be avoided," it said, warning against "external interventions."
Turkey, whose rivalry with Iran goes back to the regional battle for supremacy between the Ottoman Empire and imperial Persia, has had on occasion tricky moments in relations with Tehran.
