Nato medical team on Sunday provided medical care and assistance to the injured passengers when a bus fell into a ravine near its engineering camp in Arja, killing nine passengers.
Nato engineers and medical personnel rushed to the scene and brought 10 survivors in the emergency medical tent of the Nato Engineers' camp. Two more victims died later.
The personnel of Nato were the first to arrive on the scene with three ambulances and brought the survivors to a medical facility run by Spanish personnel supporting Nato's engineering relief work in the area.
This facility was set up on Saturday and was not yet fully operational, but the medics were still able to respond quickly and save lives.
Of the remaining eight survivors, the four critical injured were moved by ambulance to the other Nato field hospital near Bagh, which is capable of providing emergency and critical care.
The other four victims at the Arja Engineering camp will be moved to the government hospital as soon as possible. The camp's medical station is primarily intended to support engineering personnel in the event of accident and injury.
Meanwhile, Nato's medical team near Bagh, already treating hundreds of people a day, reached a new milestone on Sunday when it also opened a sophisticated 60-bed inpatient facility.
In a race against time due to winter season, Nato medics have already been caring for hundreds of people per day with medical teams visiting the area by car and foot treating the injured and sick.
In the meantime, work continued on the main hospital facility, which has started providing a range of care including complex surgical procedures.
