Baghdadi was US 'brainchild': Russian FM
"Everything was solemnly and triumphantly announced, but our military is still studying additional facts, and they cannot confirm yet much of what the U.S. has said."
Lavrov noted that ISIL emerged after the U.S. invasion of Iraq and the release of extremists from prisons by Americans.
"Therefore, to a certain extent, the Americans eliminated the one they gave birth to, if it actually happened."
Baghdadi led ISIL as it snapped up large swaths of Iraq and Syria.
U.S. President Donald Trump announced Sunday that he had been killed in a late-night raid in northwestern Syria's Idlib province.
In announcing Baghdadi's death, Trump said the ISIL leader attempted to escape via a tunnel that ultimately was a dead end, taking three young children with him "to certain death."
