DUBAI, United Arab Emirates (AP) — American rapper Macklemore said he canceled an upcoming October concert in Dubai over the United Arab Emirates' role "in the ongoing genocide and humanitarian crisis” in Sudan through its reported support of the paramilitary force that's been fighting government troops there.

The announcement by Macklemore reignited attention to the UAE's role in the war gripping the African nation. While the UAE repeatedly has denied arming the Rapid Support Forces and supporting its leader Mohammed Hamdan Dagalo, United Nations experts reported “credible” evidence in January that the Emirates sent weapons to the RSF several times a week from northern Chad.

Sudan plunged into chaos in mid-April 2023, when long-simmering tensions between its military and paramilitary leaders broke out in the capital, Khartoum, and spread to other regions including Darfur. Estimates suggest over 18,800 people have been killed in the fighting, while over 10 million have fled their homes. Hundreds of thousands are on the brink of famine.

At a contentious U.N. Security Council meeting in June, Sudan's embattled government directly accused the UAE of arming the RSF, and an Emirati diplomat angrily told his counterpart to stop “grandstanding.” The UAE has been a part in ongoing peace talks to end the fighting.

The Emirati Foreign Ministry offered no immediate comment on Macklemore's public statement Sunday, nor did the city-state's Dubai Media Office. Organizers last week announced the show had been canceled and refunds would be issued, without offering an explanation for the cancellation.

In a post Saturday on Instagram, Grammy winner Macklemore said he had a series of people “asking me to cancel the show in solidarity with the people of Sudan and to boycott doing business in the UAE for the role they are playing in the ongoing genocide and humanitarian crisis.”

Macklemore said he reconsidered the show in part over his recent, public support of Palestinians amid the ongoing Israel-Hamas war raging in the Gaza Strip. He recently has begun performing a song called “Hind's Hall,” in honor of a young girl named Hind Rajab killed in Gaza in a shooting Palestinians have blamed on Israeli forces opening fire on a civilian car.

“I know that this will probably jeopardize my future shows in the area, and I truly hate letting any of my fans down,” he wrote. “I was really excited too. But until the UAE stops arming and funding the RSF I will not perform there.”

He added: “I have no judgment against other artists performing in the UAE. But I do ask the question to my peers scheduled to play in Dubai: If we used our platforms to mobilize collective liberation, what could we accomplish?”

The RSF formed out of the Janjaweed fighters under then-Sudanese President Omar al-Bashir, who ruled the country for three decades before being overthrown during a popular uprising in 2019. He is wanted by the International Criminal Court on charges of genocide and other crimes during the conflict in Darfur in the 2000s.

Dubai, home to the long-haul carrier Emirates, the world's tallest building the Burj Khalifa and other tourist destinations, long has tried to draw A-list performers in the city-state at a brand-new arena and other venues. However, performers in the past have acknowledged the difficulties in performing in the UAE, a hereditarily ruled federation of seven sheikhdoms in which speech is tightly controlled.

That includes American comedian Dave Chappelle, who drew attention in May in Abu Dhabi when he referred to the Israel-Hamas war as a “genocide” while also joking about the UAE's vast surveillance apparatus.

Macklemore, a 41-year-old rapper born Benjamin Hammond Haggerty in Kent, Washington, won Grammy awards in 2014 for his breakout song, “Thrift Shop.”
