Muhsin Hendricks, widely regarded as the world’s first openly gay imam, was shot and killed in South Africa, according to reports on Sunday.

The imam, who led a mosque providing a safe space for LGBTQ and marginalized Muslims, was in a car with another person when a vehicle blocked their exit in Gqeberha.

“Two unknown suspects with covered faces got out of the vehicle and started firing multiple shots at the vehicle,” police said in a statement.

Hendricks, who was seated in the back, was fatally shot before the attackers fled the scene. A police spokeswoman confirmed the authenticity of a social media video that appeared to show the targeted killing in Bethelsdorp, near Gqeberha.

Authorities have not yet determined a motive and have urged anyone with information to come forward.

Hendricks, a prominent LGBTQ advocate, came out as gay in 1996 and ran the Al-Ghurbaah mosque in Wynberg near Cape Town, where he was born.
