Al Sumariya TV had cited local sources in Iraq's Nineveh province as saying Baghdadi had been wounded on Thursday in a coalition air strike
The US-led coalition fighting Islamic State said on Friday that it could not confirm a report by an Iraqi TV channel that Islamic State leader Abu Bakr al-Baghdadi has been wounded in air strikes.
A spokesman of the coalition, Colonel Chris Garver, said in an email that he had seen the reports but had "nothing to confirm this at this time".
Al Sumariya TV cited local sources in Iraq's Nineveh province that Baghdadi and other Islamic State leaders were wounded on Thursday in a coalition air strike on one of the group's command headquarters close to the Syrian border.
The channel has good connections with Shi'ite politicians and Iraqi forces engaged in the battle against Islamic State.
There have been several reports in the past that Baghdadi, whose real name is Ibrahim al-Samarrai, was killed or wounded after proclaiming himself caliph of all Muslims two years ago.
The ultra-hardline Sunni group is under increased pressure in both Iraq and Syria, and the territory under its control has shrunk significantly since 2014, limiting the potential for its leaders to move around or seek shelter.
The U.S. earlier this year announced an intensification of the war on Islamic State with more air strikes and more American troops on the ground to advise and assist allied forces.
The U.S.-led coalition has regularly flown raids out of Erbil, the capital of Iraq's Kurdistan region, in operations aimed at killing and capturing Islamic State leaders.
A Kurdish intelligence official and an Arab from the Baaj area west of Mosul said the U.S.-led coalition had conducted such a raid there earlier this week. The coalition did not confirm this raid.
Kurdish Peshmerga forces are positioned in an arc around the north and east of Mosul while the Iraqi army is trying to capture Falluja, the group's stronghold near Baghdad.
The Iraqi army is also assembling tanks and troops in south of Mosul, for an offensive planned later this year to retake the largest city under the control of the militants.
In Syria, Russian- and Iranian-backed Syrian government forces and U.S.-backed Syrian opposition and Kurds are separately trying to advance on Raqqa, the group's capital in Syria
