An Iraqi teenager stands in front of billboards in an amusement park in the northern Iraqi city of Dahuk, 50km (40 miles) from the Turkish border, October 26, 2007. For people to the south in Iraq's capital Baghdad -- where people scurry home in the late afternoon to endure nights of crackling gunfire, thudding mortars, wailing sirens and the thunder of helicopters overhead -- such a scene is but a dream. But as Turkey gears up for a potential attack on separatist PKK rebels hiding in Iraqi Kurdistan's mountains, fear is rising here that this region's stability too may crumble.
