The U.S.-led coalition fighting Islamic State said on Friday 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.
