Operation Mountain Storm

Since October 7, 2001 following the September 11, 2001 attacks, the United States has been engaged in a war in Afghanistan as a part of War on Terror.

From May 1996, Osama bin Laden had been living in Afghanistan along with other members of al-Qaeda, operating terrorist training camps in a loose alliance with the Taliban. Following the 1998 US embassy bombings in Africa, the US military launched cruise missiles at these camps with limited effect on their overall operations. A follow-on plan, called Operation Infinite Resolve, was planned but not implemented.

The UN Security Council had issued Resolutions 1267 and 1333 in 1999 and 2000 directed towards the Taliban which applied financial and military hardware sanctions to encourage them to turn over bin Laden to appropriate authorities for trial in the deadly bombings of two U.S. embassies in Africa in August 1998, and close terrorist training camps.

After the September 11, 2001, attacks, investigators rapidly accumulated evidence implicating Osama bin Laden. In a taped statement, bin Laden publicly acknowledged his and al-Qaeda's direct involvement in the 9-11 attacks. In an audiotape posted on a website that the U.S. claims is "frequently used by al-Qaeda", on May 21, 2006, bin Laden said he had personally directed the 19 hijackers.

The war in Afghanistan (2001–present) began on October 7, 2001, as Operation Enduring Freedom, a response to the September 11, 2001 attacks on the United States of America (U.S.). This marked the beginning of the U.S. War on Terrorism. The stated purpose of the invasion was to capture Osama bin Laden, destroy al-Qaeda, and remove the Taliban regime which had provided support and safe harbour to al-Qaeda.
