An air strike by the U.S.-led coalition has killed Rayan Mdeshaal, the founder of the Daesh propaganda media outlet Amaq, in the eastern Syrian province of Deir al-Zor, his brother said in a Facebook post.
There was no immediate comment from the United States-led coalition against Daesh.
The Facebook post on Wednesday May 31 said the strike killed Rayan Meshaal and his daughter in their home in the city of al-Mayadin. Syrian opposition activists had been sharing news of Meshaal's death on social media.
"I'm pleased to announce the martyrdom of my older brother Baraa Kadek, known as Rayan Meshaal...in an air strike by the coalition," the Facebook post said.
Daesh often claims responsibility for attacks worldwide through Amaq channels on social media.
Rita Katz, director of the U.S.-based SITE monitoring service, said on Twitter that a coalition strike allegedly killed Meshaal in Deir al-Zor.
Katz added Amaq had "shown itself as Daesh state media agency" since its founding in 2014 and had issued claims for at least two dozen attacks around the world.
Daesh militants control swathes of Syria's vast eastern deserts and most of Deir al-Zor province bordering Iraq, but they have been on the back foot over the past year.
The Syrian Observatory for Human Rights said air strikes in al-Mayadin last week killed more than 100 people including 40 children and other family members of Daesh fighters.
