The United States on Wednesday doubled to $10 million its reward for the capture of the ISIS supremo, Secretary of State Mike Pompeo announced.
The US had already offered $5 million for Amir Mohammed Abdul Rahman al-Mawli before he was identified as the successor to Abu Bakr al-Baghdadi, who was killed by US commandos in an October raid in Syria, AFP reported.
Born in 1976, al-Mawli issued edicts to justify the persecution of the Yazidi minority, a campaign that the United Nations has described as genocide.
The militants killed thousands of Yazidis and abducted and enslaved thousands more women and girls as they rampaged across the Middle East.
Al-Mawli was born in the Iraqi city of Mosul.
