NATO's International Security Assistance Force Joint Command, which was in charge of combat operations, lowered its flag, formally ending its deployment.
US Gen. John F. Campbell, commander of NATO and US forces, said that the mission now would transition to a training and support role for Afghanistan's own security forces, which have led the fight against the Taliban insurgents since mid-2013.
"The Afghan security forces are capable," Campbell said. "They have to make some changes in the leadership which they're doing, and they have to hold people accountable."
The mission ends as the Taliban is increasing its attacks. US President Barack Obama recently allowed US forces to launch operations against both Taliban and al-Qaida militants, broadening the mission of the US forces that will remain in the country after the end of the year.
Violence continued today in the country, as suicide bombers launched an assault on a police station in southern Kandahar province. Police killed three suicide bombers, said Samim Akhplwak, the spokesman for the provincial governor. He said casualty figures were unclear.
Up to 10,800 US troops will remain in Afghanistan for the first three months of next year, 1,000 more than previously planned as the new mission, called Resolute Support, waits for NATO partners to deploy, said a NATO official who spoke on condition of anonymity to discuss troop deployments.
Today's ceremony was the first of two that will draw a formal close to NATO's combat mission by Dec. 28.
