MOSUL: On the western side of Mosul, much of the fighting against Daesh militants takes place between houses so close that they almost touch. Snipers fire from roofs and through holes blasted into outer walls.
Seen through these holes, this part of Iraq鈥檚 second-largest city is a landscape of half-collapsed buildings, burned-out cars and rubbish-strewn streets. Helicopters hover and barricades of sandbags block the streets.
This front line near the old city is where police officer Mayser Suleyman Karim marked his 33rd birthday with the rest of his unit.
The extremists who took over the city in 2014 were driven out of eastern Mosul by Iraq鈥檚 elite counterterrorism force in January. Much of the fighting in the city鈥檚 western districts, however, has been done by the heavily militarized federal police force.
During a momentary pause in the battle, Mayser recalled that he had joined the force in the aftermath of the mosque bombing in Samarra on Feb. 22, 2006. That is when suspected Al-Qaeda militants blew up the Al-Askari shrine, starting a wave of sectarian violence in which thousands died.
鈥淚t has been a long time now 鈥� 10 years. No, 11 years actually. I鈥檓 tired,鈥� Mayser said apologetically.
鈥淔or how long can you keep doing this?鈥� he asked. 鈥淵our joints start to hurt, movement is difficult, cannot run. ... It鈥檚 not about being scared, I鈥檓 just getting tired. My body is getting tired.鈥�
Part of the police unit鈥檚 work in western Mosul involves manning checkpoints and interacting with civilians, some of whom remain in the area despite the fighting.
Many police are instinctively wary: They come from distant parts of Iraq, know little of Mosul and suspect that militants or their supporters might have blended into the population. Security forces have been hit by suicide attacks from the militants.
Mayser said he wanted to quit his job but did not have any options at the moment.
鈥淚t鈥檚 good that I鈥檓 not married. But there are guys here who are married and have kids. Their situation is more difficult than mine,鈥� he added.
The police unit sometimes harasses militants by firing mortars at them over the buildings. That is one reason the city has been wrecked so badly.
According to a terrain analysis done by the UN, there is about 2陆 times more destruction in western Mosul than in the eastern half, and the extremists have not been fully driven out of the west yet.
Government artillery units also pour vast amounts of fire into the parts of the city under Daesh control. Airstrikes target snipers, sometimes bringing down several buildings in the hunt for a single militant.
It is hard to be sure how many civilians have been killed or wounded since the battle for western Mosul began nearly two months ago.
The UN said at least 300 people have been killed, while the Nineveh provincial health department reckons that the real number could be closer to 1,000. At least 1,600 cases of trauma have been admitted to Iraqi and Kurdish hospitals since Feb. 18.
After a day鈥檚 work, the police unit returned to its base, and the men collapsed onto broken chairs and sofas.
Mayser said the brutality of the war 鈥� seeing friends get killed or wounded 鈥� had made him stronger. But it has also made him less sensitive to suffering.
鈥淣ow I鈥檓 ignoring everything that happens, no matter how small or big. Your mother or your father getting ill, things like that, I鈥檝e seen worse than this,鈥� he said.
Meanwhile, the six-month-old operation has forced around half a million people to flee their homes, the UN said.
鈥淭he sheer volume of civilians still fleeing Mosul city is staggering,鈥� Lise Grande, the UN鈥檚 humanitarian coordinator in Iraq, said in a statement.
鈥淥ur worst case scenario when the fighting started was that up to one million civilians may flee Mosul. Already, more than 493,000 people have left, leaving almost everything behind,鈥� she said.
