The Battle of Abu Ghraib was a battle between Iraqi Mujahideen and United States forces at Abu Ghraib prison on April 2, 2005. Mujahideen linked to Al-Qaeda in Iraq launched a surprise attack on the American section of Abu Ghraib prison, known as Camp Redemption, by firing heavy mortars and rockets at the facility, and then assaulting with small arms, grenades, and vehicle-borne improvised explosive devices. The attempted siege was successfully repelled by the US forces after four hours, resulting in over 40 wounded in action, and an estimate 70 insurgents were killed.
