The announcement made by Iraqi military was the latest unconfirmed report of the possible death or injury of Baghdadi while a Twitter site which publishes statements from ISIS has termed the announcement false.
"Iraqi air forces have bombed the convoy of the terrorist Abu Bakr al-Baghdadi while he was heading to Karabla to attend a meeting with Daesh commanders," said a statement issued by the Iraqi military.
The US military also declined to comment on the Iraqi military's claim.

"Baghdadi's self-proclaimed caliphate in large areas of Iraq and Syria would survive even if he had been killed," said an ISIS supporter on Twitter.
Baghdadi has galvanised militants from around the world, encouraged by his military successes and plans to redraw the map of the Middle East to create a self-sustaining caliphate.
Coalition forces led by US launched air strikes against ISIS in Iraq and Syria last year while Russia, which has launched a bombing campaign in Syria has also termed ISIS as its enemy.
