In 2001, after 19 militants associated with al-Qaeda staged the September 11 attacks, the United States led a coalition that overthrew the Taliban in Afghanistan. In December 2001 bin Laden went into hiding after evading capture by U.S. forces in the Tora Bora cave complex. In the following years, U.S. forces searched for him along the Afghanistan-Pakistan border, during which time bin Laden remained absent from the public eye. Then in October 2004—less than a week before that year’s U.S. presidential election—bin Laden emerged in a videotaped message in which he claimed responsibility for the September 11 attacks. After that he periodically released audio messages, including in 2008, when he threatened retaliation for the deaths of Palestinians in the Gaza Strip, and in 2009, when he challenged the nerve of the new U.S. president, Barack Obama, to continue the fight against al-Qaeda.
