Osombie (movie, 2012)

Following the 9/11 attacks, the war on terror against Afghanistan continues. With the Taliban insurgents hiding out in the mountains however, they become increasingly difficult for the US military to engage. The solution is to try and flush them out by adding low level chemicals to the water supply. Little do the USA know however that enemy scientists have adapted the chemicals to make their own formula, one that can bring the dead back to life.
