A missile "malfunction" during a US airstrike on the Afghan capital Kabul has resulted in several civilian casualties, NATO says.
The strike was reportedly launched in response to rocket attacks that had targeted Kabul's airport and surrounding areas several hours after US Defense Secretary Jim Mattis and NATO Secretary General Jens Stoltenberg arrived in the country on Wednesday.
"Tragically, one of the missiles malfunctioned, causing several casualties," said a statement released by NATO.
"Resolute Support deeply regrets the harm to non-combatants. An investigation into the attack and the malfunctioning ammunition has begun," it added.
The attack on the airport, which killed one person and wound 11 others, was claimed by both the Taliban and the Daesh terrorist groups.
