IRNA � Constructive criticism and lawful gatherings are productive and will prepare the ground for positive change and improvement in the society, Iranian President Hassan Rouhani said.

Officials should find the cultural and social reasons behind the events and be accountable to the people's demands, President Rouhani said late on Tuesday in a meeting of the Supreme Council of Culutral Revoultion.

'Standing against those who insulted the sanctities and the country's flag on one hand, and demonstrating solidarity among parties, ethnic groups and religions against the rioters on the other, brought another victory over the enemies,' the president added referring to recent unrests in a few Iranian cities in protest to the economic conditions of the country.

President Rouhani also appreciated the security, intelligence, police, IRGC and Basij forces for their vigilance to manage the recent incidents in the country.
