United Nations Secretary-General Antonio Guterres has expressed concern over “a disturbing rise in anti-Muslim bigotry.”

He's calling on governments to protect religious freedom and for online platforms to curb hate speech.

Guterres made the remarks on Saturday to mark the International Day to Combat Islamophobia marked every year on March 15.

Rights groups around the world and the UN have noted a rise in Islamophobia, anti-Arab bias, and anti-Semitism since the start of Israel’s 17-month war in Gaza.

“We are witnessing a disturbing rise in anti-Muslim bigotry. From racial profiling and discriminatory policies that violate human rights and dignity, to outright violence against individuals and places of worship,” the UN chief said in a video post on X.

“This is part of a wider scourge of intolerance, extremist ideologies, and attacks against religious groups and vulnerable populations.”

He called on governments, without specifying any one nation, to “foster social cohesion and protect religious freedom”.

“Online platforms must curb hate speech and harassment. And we must all speak out against bigotry, xenophobia and discrimination,” he added.

Meanwhile, UN Under-Secretary-General Miguel Angel Moratinos said Muslims were facing “institutional discrimination and socioeconomic restrictions”.

“Such biases are manifested in the stigmatization and the unwarranted racial profiling of Muslims and are reinforced by biased media representations, and by the anti-Muslim rhetoric and policies of some political leaders,” he said in a speech to the UN General Assembly.

Rights advocates have for years raised concerns about the stigma faced by Muslims and Arabs because of how some people conflate those communities with armed groups.
