DUBAI - A Twitter account Iran experts believe is run by the office of Supreme Leader Ayatollah Ali Khamenei said on Tuesday "arrogant" powers had tried hard to bring the Islamic Republic to its knees but had failed.
In a comment apparently referring to the failure of Iran and six world powers on Monday to end a 12-year dispute about Iran's nuclear goals, a message on the English-language account said: "In the nuclear issue, arrogants have made their best to bring Iran to its knees but they were not able and will not be able to do so."
