Nowruz, or the Persian New Year, marks the first day of spring, and is celebrated by a wide range of people from South Asia to Southeastern Europe.
The observance extends into Persian antiquity when the country was ruled by Zoroastrians. As such, some ultra-conservative Iranian mullahs want to ban the celebration as un-Islamic. Nowruz is also a holy day for Sufis, Ismailis, Alawites, Alevis, and Bahais.
Here are some views of people in the region celebrating Nowruz.
