December 25 the Golden Division attacked the Quds district on the outskirts of east Mosul. On December 26 the Islamic State counter attacked there with three car bombs all of which were destroyed. This was the first movement by the Iraqi forces (ISF) in east Mosul in several days after they were paused to recover from two months of heavy fighting.
IS was also said to be changing their tactics inside the city. The group has been relentlessly shelling the eastern half of Mosul. Mortar fire for example, killed two civilians on December 26. Their firing positions however have been targeted by the U.S. led Coalition and Iraqi forces. The militants were now said to be mounting mortars on vehicles so that they could fire, quickly change positions and then fire again before they were spotted and destroyed.
The last two days air strikes have been blamed for civilian casualties inside Mosul. On December 26 seven civilians were wounded in one such incident. It can only be speculated whether this was done by the U.S. led Coalition or the Iraqis.
All of the rest of the news was on plans for the new Mosul campaign. Reuters said that U.S. troops would be inside Mosul itself to provide front line targeting for air strikes and advice to the Iraqi forces. It along with Iraqi News also noted that more troops and police were moving into eastern Mosul to reinforce the units already there, while Al Alam reported that the ISF were fortifying their positions in northern and eastern Mosul.
