The United States Department of Defense released video on Monday (October 24) purporting to show the destruction from an air strike on a militant facility near the northern Iraqi city of Mosul.
The ministry released a cockpit video showing the strike, which it said hit an Islamic State repeater tower on October 16.
The Iraqi army and the Kurdish Peshmerga forces began moving in the direction of Mosul at dawn on October 17 under air cover from the U.S.-led anti-Islamic State coalition, after Iraqi Prime Minister Haider al-Abadi announced the start of the offensive on Mosul, two years after Iraq's second-largest city fell to the militants.
The fall of Mosul would effectively signal the defeat of the ultra-hardline Sunni group in Iraq. Islamic State also controls parts of Syria.
The Iraqi army is attacking Mosul on the southern and southeastern fronts, while the Peshmerga carried out their operation on the eastern front.
Mosul, with a current population of 1.5 million, is the largest city still under control of the militants, followed by Raqqa, in neighboring Syria. Islamic State declared a over parts of the two countries in 2014.
