Why are US troops in Afghanistan?
American-led combat operations against the Taliban officially ended in 2014, but some US troops remain in the country to provide training and assistance to Afghan forces, which do most of the fighting.
The Taliban’s power and reach has surged since then – and the number of security personnel being killed has soared.
Last year, US President Donald Trump signalled he would keep US boots on the ground indefinitely amid concerns that the Taliban was gaining ground.
The US forces are part of the Nato-led Resolute Support Mission in Afghanistan, which has more than 16,000 personnel.
