AERIAL SHOTS of buildings, houses and the destroyed 12th century Great Mosque of al-Nuri in the old western side of Iraq's northern city of Mosul. IS chief Abu Bakr al-Baghdadi made his only confirmed public appearance in July 2014 at the Al-Nuri mosque, where he declared the establishment of a "caliphate". Three years later Iraq's army and a US-led international coalition had forced the jihadists out of Iraq's second city. The Al-Nuri mosque, and the adjacent leaning minaret -- nicknamed Al-Hadba or the "hunchback" -- were destroyed in June 2017 during the battle to take back the city. STOCKSHOTS
