"To the Youth in Europe and North America" is an online open letter written on January 21, 2015 by Iran's Supreme Leader, Ayatollah Ali Khamenei. According to Al-Monitor, it may be the first time that young people in the West have been directly addressed by a senior Islamic cleric about his religion.
Prompted by the Charlie Hebdo shooting in Paris on 7 January 2015 by militants who said that they had acted in the name of Islam,
and by the current image of Islam in the West, Khamenei released the letter on his official website and promoted by a Twitter account attributed to him.
