Iraq's Defence Ministry has released footage showing airstrikes on dozens of vehicles described as a convoy of Islamic State fighters fleeing the western city of Fallujah following its recapture by the Iraqi military.
Scores of militants are thought to have been killed in the airstrikes, which authorities lauded as an operation carried out exclusively by the Iraqi military.
"More than 20 helicopters took part in the mission and were able to destroy more than 138 vehicles," Iraqi army commander Lieutenant General Hamid al-Maliki said.
Al-Maliki, who is speaking in the footage released by the Defence Ministry late on Wednesday night, said Iraqi helicopters carried out all of the strikes.
"No other force took part in the operation," he said.
The US-led coalition said on Thursday that they also conducted airstrikes on "two large concentrations of Daesh vehicles and fighters," according to spokesman Colonel Christopher Garver.
Daesh is an Arabic name for the Islamic State group.
The strikes came in waves.
Iraqi air force and coalition planes began attacking one convoy late on Tuesday night and into Wednesday morning and a second group of IS vehicles on Wednesday.
Over the course of the two days, the coalition strikes were estimated to have destroyed 175 suspected IS vehicles, according to a statement from Garver.
He said "we know the Iraqi security forces destroyed more" vehicles.
Iraqi forces declared the city of Fallujah fully liberated on Sunday, after government troops pushed the remaining IS fighters out of the city's north and west under close cover of US-led coalition airstrikes.
Hundreds of IS fighters were suspected to have escaped the city during the month-long operation, according to Iraqi commanders on the ground.
IS has suffered a string of military defeats in Iraq over the past year.
At the height of the group's power, in 2014, IS controlled nearly a third of Iraq, having blitzed across large swaths of the country's north and west and captured Iraq's second-largest city of Mosul.
Now the group is estimated to control 14 per cent of Iraqi territory, according to the office of Iraq's prime minister.
