Singer Pharrell Williams and Iranian President Hassan Rouhani both took to Twitter to react to the news that six young Iranians were arrested after they posted a video of themselves last month dancing to Pharrell's hit song "Happy."

Pharrell linked to a New York Times story on the six "Happy in Tehran" dancers, who were forced to appear on state television Tuesday to repent what they had done.

It's beyond sad these kids were arrested for trying to spread happiness http://t.co/XV1VAAJeYI

And Rouhani, who was elected president last year on a platform of moderation and reform, and who has decried Internet censorship, responded today by posting an excerpt of his June 2013 victory speech.

" #Happiness is our people's right. We shouldn't be too hard on behaviors caused by joy." 29/6/2013
