Where did the taliban and al-qaeda flee to as the war in afghanistan went against them?

Iran

Explanation:

The war in Afghanistan was a war that initially faced the Islamic Emirate of Afghanistan, ruled by the Taliban, and, once overthrown, its insurgency, on the one hand, and an international coalition commanded by the United States, for control of the Afghan territory, and that continues as War of Afghanistan (2015-present). It began on October 7, 2001 with the "Operation Enduring Freedom" of the US Army and "Operation Herrick" of British troops, launched to invade and occupy the Asian country. The invasion was unleashed in response to the attacks of September 11, 2001 in the United States, of which this country blamed Osama bin Laden. To begin the invasion, the United States relied on a peculiar interpretation of Article 51 of the Charter of the United Nations, on the right to self-defense.

The declared objective of the invasion was to find Osama bin Laden and other al Qaeda leaders to bring them to trial, and to overthrow the government of the Islamic Emirate of Afghanistan ruled by the emir mullah Omar, who in the opinion of the Western powers supported and gave refuge and coverage of Al Qaeda members. The Bush Doctrine of the United States declared that, as a policy, no distinction would be made between terrorist organizations and nations or governments that give them refuge.
