The NATO-led international coalition is set to end active combat in Afghanistan and convert to a training and advisor mission, military officials said Sunday, according to dpa. A ceremony was being held in Kabul on Sunday to mark the end of 13-year old International Security Assistance Force combat mission in Afghanistan. The new Resolute Support Mission will see some 13,000 foreign troops acting as trainers and advisors for Afghan forces from January 1. The international troops will come from 28 NATO allies and 14 other partner nations. They will not lead any combat operations. NATO-ISAF was set up with a UN Security Council mandate to help provide security and develop new Afghan forces, after a US-led invasion ousted Taliban regime from Kabul in 2001. At its peak there were 140,000 troops from 51 countries. More than 3,500 foreign troops died in the Afghan war theatre.
