The UN’s Office for the Coordination of Humanitarian Affairs said, "Following the intensification of military operations in Mosul city on 29 December, the rate of displacement from Mosul has increased markedly, with over 9,000 people having fled the city in the space of four days."
In the offensive launched on October 17 to retake what is now the Islamic State group s last major stronghold in the country, Iraqi forces started a fresh push last week, engaging in heavy fighting in eastern Mosul .
A senior commander from the elite Counter-Terrorism Service that has done most of the front-line fighting inside the city told AFP on Sunday that Iraqi forces now controlled more than 60 percent of Mosul s eastern half.
Officials said that it could be months before Iraqi forces are able to completely retake Mosul , Iraq s second city, where hundreds of thousands of civilians still live.
Some were forced to stay by IS, others remained for fear of losing their property, because winter conditions in displacement camps are harsh or simply because escape routes are not safe enough.
