>> Iraqi coalition forces are on the move. This time pushing into Western Mosul, the heart of Islamic State territory in Iraq. A new offensive after months of fighting in the city's east. Hundreds of troops in tanks and armored vehicles, backed by air power, set off for the operation early on Sunday.
Resting control of several villages and a local power distribution station at the offset of the battle, paving the way for troops to move towards Mosul's airport, the first target of a ground offensive that officials admit will be a tough fight. Iraqi Prime Minister announcing the start of the battle in a televised speech, asking Iraqi forces to respect human rights during the battle.
>> We call on our brave troops to start the push to liberate the rest of the city, and to liberate people from the oppression and terrorism of Islamic State. Taking care of people, and dealing with them in a humanitarian way. And providing all the necessary requirements for the displaced people as you did before, you brave fighters.
> On Saturday, Iraqi planes dropped millions of leaflets to warn residents of the imminent battle. Humanitarian organizations have voiced concern about the thousands that will be trapped. Up to 400,000 civilians could be displaced by the offensive. While residents suffer food and fuel shortages. And those armored vehicles will find it difficult to navigate though its narrow streets and dense population.
Defeat in Mosul would be a huge loss for Islamic State, it's Iraq's second largest city and the de facto capital of the militant's self-declared caliphate.
