A notorious ISIS fighter featured in the shocking video this month of a boy appearing to execute two prisoners with a handgun has been killed in battle, a counter-terrorism official said today.

Abu Saad al-Dagestani was the nom de guerre of an ISIS terrorist shown in the gruesome Jan. 13 tape overseeing what ISIS claimed was the execution of two alleged "Russian spies" by a boy under 11. Al-Dagestani was first reported killed in jihadi tweets on Jan. 15, which claimed he was "martyred" near the embattled Kurdish town of Kobani on Syria's border with Turkey.

"We do think he was killed," a counter-terrorism official familiar with military operations around Kobani by the U.S.-led coalition told ABC News today.

ISIS Video Claims to Show Child Executioner

The video, apparently produced by an ISIS media outlet and shared on Twitter, was seven minutes long and featured “confessions” by the two men. In a heavily-edited section, the boy, called a “lion’s cub,” was shown firing a pistol at the heads of the men, who each fall, apparently lifeless.
