The Afghan war between US-lead Nato forces and Taliban insurgent groups was triggered by the attack on the World Trade Centre in New York and Pentagon on September 11, 2001. It has cost more than 3,000 lives on the Nato side and some 13,000 civilian lives. On May 2, 2011, Osama bin Laden, a major target of the war, was killed by US special forces.
Afghan security forces are struggling to hold off increasingly powerful Taliban militants as slow-moving peace talks continue between warring factions in the country. But while negotiations continue, a May 2021 deadline for the withdrawal of US troops from Afghanistan is nearing. The departure of US forces is of great concern to the Hazara people, one of the most oppressed groups in Afghanistan. Unsure if their government can protect them after the Americans leave, ethnic Afghan Hazara people have started joining militia groups.
