The Taliban also angered other countries by allowing suspected terrorists to live freely in Afghanistan. Among them were Osama bin Laden and members of the al-Qaeda terrorist network. In September 2001, the United States blamed bin Laden for the terrorist attacks on the World Trade Center in New York City and the Pentagon outside Washington, D.C. The Taliban refused to hand him over to the United States. In response, the United States and its allies launched a bombing campaign against al-Qaeda in October 2001. Within months the Taliban abandoned Kabul, and a new government led by Hamid Karzai came to power, but fighting between the Taliban and US-led armies continued. Taliban fighters have gone into Afghanistan from neighboring Pakistan. Afghans accuse Pakistan's military of being behind the Taliban militants but Pakistan has rejected this and stated that a stable Afghanistan is in Pakistan's own interest.
