On September 11, Taliban foreign minister Wakil Ahmed Muttawakil "denouncethe terrorist attack, whoever is behind it", but Mullah Omar immediately issued a statement saying bin Laden was not responsible. The following day, President Bush called the attacks more than just "acts of terror" but "acts of war", and resolved to pursue and conquer an "enemy" that would no longer be safe in "its harbors". The Taliban ambassador to Pakistan, Abdul Salam Zaeef, said on September 13, 2001, that the Taliban would consider extraditing bin Laden if there was solid evidence linking him to the attacks. Though Osama bin Laden eventually took responsibility for the 9/11 attacks in 2004, he denied having any involvement in a statement issued on September 17, 2001, and by interview on September 29, 2001.
