IRNA � Iranian Ambassador to the UK Hamid Baeedinejad said on Wednesday that all the states and news/social media should act responsibly not to incite violent riotings.

Writing on his official Twitter account, he was reacting to the recent protests in Tehran and other Iranian cities and voices of support for violent rioters by certain states and media.

'All governments must guarantee freedom of expression as a basic civil right,' the ambassador said, adding, 'They should also prevent violent riots aimed at public disorder and human casualties.'

'All States and news/social media should act responsibly not to incite violent riotings,' Baeedinejad said.

However he regretted that 'double standards prevail'.
