(CNN)Here's a look at Operation Enduring Freedom, which began on October 7, 2001 with allied air strikes on Taliban and al Qaeda targets. The United States linked the September 11, 2001 terrorist attacks to al Qaeda, a group that operated under the Taliban regime's protection in Afghanistan. The operation was launched to stop the Taliban from providing a safe haven to al Qaeda and to stop al Qaeda's use of Afghanistan as a base of operations for terrorist activities.
