The famous leaning minaret of Mosul in northern Iraq has been restored using its original brickwork, years after it was reduced to rubble under Islamic State group rule. The Al-Hadba or "hunchback" minaret is part of the historic Al-Nuri Mosque from where former IS chief Abu Bakr al-Baghdadi in July 2014 declared his so-called "caliphate" that spread horror across swathes of Syria and Iraq.
