An Arab satellite television network report claimed Thursday that a US-led coalition airstrike against Islamic State targets in areas they control has killed a “large number” of the organization’s top commanders.

It is not yet clear if ISIS’ top leader, Abu Bakr al-Baghdadi, was killed.

The report on Al Arabiya television quoted sources in the US-led coalition as saying that the airstrike at a location on the Syria-Iraq border resulted in the deaths of “dozens” of top ISIS commanders.

The group was meeting in the city of Ka’im, and coalition forces, alerted to the meeting by ground intelligence, took advantage of the situation to eliminate the commanders.

Iraqi sources said that al-Baghdadi was set to attend the meeting, and may have been on his way there when the coalition planes struck. The fighters that carried out the strike were flown by French pilots.

Reports from the region indicated that coalition forces struck hard in a number of ISIS-controlled cities, and that damage across the area occupied by the terror group was widespread.

Witnesses said that ISIS militia ordered people to remain in their homes until further notice, and that fresh forces from neighboring states had poured in to help fight the coalition forces.
