Iraqi pro-government forces patrol the eastern part of the embattled Iraqi city of Mosul on December 28, 2016, during an ongoing military operation against Islamic State (IS) group jihadists. Iraqi forces have advanced into eastern Mosul -- which is divided by the Tigris River -- and have retaken some neighbourhoods on that side of the city, which has been held by the Islamic State group for more than two and a half years. / AFP PHOTO / AHMAD AL-RUBAYE
