Support for protests in Iran is still rising among international celebrities, with Justin Bieber joining the crowd as hijab victim Mahsa Amini’s hashtag has reached 100 million.

The Canadian popstar used his platform of about 260 million followers on Instagram to raise awareness about the current uprising in Iran with a story of Iranian protesters holding a photo of Mahsa Amini, whose tragic death in the custody of hijab police triggered worldwide rallies against the Islamic Republic. 

The Persian hashtag that has been trending in support of Mahsa, also known as Zhina or Jina, has been retweeted more than 100 million times, and still counting. 

This is by far the highest number of retweets in the history of Twitter, about 25 times more than the trendiest hashtags on the social media platform so far. This has been achieved thanks to numerous celebrities and political figures as well as human rights activists and organizations. 

Iranian celebrities, both from inside the country and abroad as well as athletes from many national teams have expressed support for the uprising despite repeated threats and warning by authorities about banning them from their professions. 

Several foreign singers and artists have also dedicated pieces to the 22-year-old Mahsa, including pop singer Chris de Burgh and community-driven rock star Yungblud.

Legendary co-founder of Pink Floyd Roger Waters has posted a few times since last week, expressing anger over Mahsa’s death.
