TEHRAN — The northwestern Iranian city of Urmia has been on edge in recent days, with a group of pro-government demonstrators engaging in hate speech against the local ethnic Kurdish community.

The tensions erupted after Shiite mourning ceremonies, marking the martyrdom anniversary of the religious group's most revered figure — Imam Ali — coincided with Nowruz, the Iranian New Year, widely celebrated by the Kurds, who are mostly followers of Sunni Islam. 

Urmia, the capital of West Azerbaijan province, has long been home to a diverse population, including Kurds and Turkish-speaking Shiite Azeris. Despite interethnic differences, the city has largely maintained a reputation of being peaceful and tolerant.

While Nowruz is celebrated across Iran, for the country's Kurds it holds additional significance as a symbol of cultural identity and resistance. This year's ceremony in Urmia saw a large, colorful gathering of Kurds who were dancing, prompting a pro-government Shiite cleric to issue calls for rallies in protest against what he framed as an insult to Shiite sanctities.
