Official end to Afghan war for US and Nato

The United States and Nato have formally ended their war in Afghanistan with a ceremony at their military headquarters in Kabul.

The symbolic ceremony marked the end of the US-led International Security Assistance Force, which will transition to a supporting role with 13,500 soldiers, most of them American, starting on January 1.
