First up today, authorities are investigating an accident that led to the deaths of seven U.S. Marines. It happened Wednesday night when two military helicopters collided in midair. The crash took place during a training operations near a Marine base in Arizona. Arizona's governor said it's a reminder that no military mission is ever routine, whether it's in combat or in training. The two helicopters that were involved in the crash were a Super Cobra attack helicopter and a Huey utility chopper. The Marines on board were getting ready to deploy to Afghanistan, and that's why they were training in Arizona, because the terrain there is so similar to what they would experience overseas. The tension in parts of Afghanistan does not look like it 'll ease up any time soon. This, of course, is related to the coalition forces admitting that they accidentally burned some copies of the Quran, Islam's holy book. President Obama apologized yesterday to Afghanistan's president for the, quote," error." Meantime, hundreds of Afghans have been protesting for days, sometimes outside of military bases in the country. Afghan officials who are investigating the situation have urged the protesters to avoid resorting to violence.
