The brutal fight to rid Mosul of so-called Islamic State has left the northern Iraqi city in ruins, thousands dead and survivors scattered far and wide. Just how much devastation was caused by the battle between Iraq’s forces - backed by US-led air strikes - and the militant group, and what will happen now?

While the battle for Mosul is over after nine months of fighting, its people are facing a humanitarian crisis on a catastrophic scale.

The Old City has been hit badly

Death toll estimates vary widely, from thousands to tens of thousands, and more than one million - equivalent to the population of Dublin - have fled their homes since the offensive started in October last year.

Whole neighbourhoods have been flattened, bodies remain under rubble and streets are littered with unexploded weapons, landmines and booby-traps.

Much of Iraq’s second city, controlled by IS since June 2014, has been reduced to rubble.

The mission is now regarded as the single largest urban battle since World War II.

Tale of two cities

All parts of Mosul have experienced some kind of damage, according to the latest UN assessment. However, the western half of the city, retaken in July, has suffered more than in the east - won back from IS six months earlier.

More than half of Mosul's 54 western residential districts have been significantly affected.

The UN describes 15 as “heavily damaged,” meaning most buildings are uninhabitable.

A further 23 districts are “moderately damaged,” meaning up to half of the buildings have been destroyed or are structurally unsound, and 16 districts are “lightly damaged”.
