The U.S. military says it has targeted Islamic State leaders in Iraq.
Senior U.S. defense officials said a series of air strikes destroyed a convoy of 10 vehicles near the northern city of Mosul on November 7.
The officials could not confirm whether the top Islamic State leader, Abu Bakr al-Baghdadi, was among those targeted, although some reports said he had been wounded.
Al-Baghdadi has declared himself the caliph, or supreme leader, of the vast areas of territory in Iraq and Syria under IS control.
Elsewhere on November 8, a series of bombings in and around the capital Baghdad killed at least 43 people.
In the worst attack, 11 people were killed and 21 wounded in a car bombing in Baghdad's Shi'ite district of Sadr City.
Meanwhile, in neighboring Syria, a Syrian rights group has reported that government forces conducted air raids on a northern town held by the Islamic State militant group.
The Britain-based Syrian Observatory for Human Rights said on November 9 that government helicopters dropped seven barrel bombs and warplanes fired on the town of Al-Bab northeast of Aleppo late on November 8, killing at least 21 people and wounding some 100 others.
There was no word on casualties among IS fighters in Al-Bab.
The air raids are a rare attack on IS positions from the Syrian government, which has so far concentrated its attacks on groups further south, especially around Damascus.
A U.S.-led coalition has, without Syrian government consent, been conducting air strikes against IS positions in northern Syria, particularly around the besieged Kobani near the Turkish border, for several weeks.
