Iraqi jets carried out, on Wednesday, airstrike resulted in the destruction of the headquarters of the so-called "Islamic police" belonging to ISIS in the area of ​​Baaj west of Tal Afar. Local sources and Iraqi security sources said that at least 50 civilians were killed and many others were injured, by air strikes, targeting various residential areas in the western coast of Mosul.

At a conference on future wars held, in Washington, on Tuesday, General Mark Millie pointed out that global population growth and the massive increase in the number of cities with more than 10 million people make it imperative for armies to be eligible to fight in densely populated areas.

"Aleppo, Mosul and Falluja are living models of future wars, and we are likely to see a fundamental change in the fields in which wars will take place, as battlefields will move from open to densely populated areas," Milley said.

The US general stressed the need to rehabilitate infantry and special forces to be able to fight a new kind of warfare. The US military, however, has to develop its armament and organization in accordance with this development, he added.

 "We have to think based on that in the size and weight of the tanks, the lengths of the helicopters and the dimensions of the vehicles and other military equipment used in street fighting," he stated.

Milley said the Army also must be prepared to engage in cyber warfare, operate without the space-based communications and precision navigation it has taken for granted, and fight in a complex urban setting.

Local and Iraqi security sources said, Wednesday, that at least 50 civilians were killed and dozens injured by Iraqi airstrikes on different areas of the city on the western coast of Mosul. The bombing continued, according to sources, for hours last night, in an attempt by Iraqi forces, backed by Washington, to make new progress in the neighborhoods, which are still under the control of ISIS.

Iraqi government forces recaptured eastern Mosul in January and launched an offensive in February to recapture the western region.Iraqi troops are currently working to retake central Mosul districts from IS militants, specifically eyeing the city’s grand mosque where the group’s self-styled “Caliphate” was declared in 2014.

Iraqi and U.S.-led coalition generals have admitted that battles in western Mosul were much more difficult due to the region’s high population and the complex structure of its residential areas.

On the other hand, The number of refugees displaced by battles between Iraqi security forces and Islamic State militants in Mosul reached 415.000 since security operations launched in October, according to an Iraqi rights group.

This is the number of people displaced since the Iraqi government launched a U.S.-backed offensive to recapture Iraq’s second largest city and IS’s largest stronghold in Iraq, according to the Iraqi Observatory for Human Rights.
