Iranian rescue workers have spotted the bodies of 30 passengers of an Aseman Airliner that crashed with 66 people on board in the country's mountainous southwest on Sunday.

Mountain climbers and rescue workers who had reached the site of the plane crash said on Tuesday that 15 of the bodies were identifiable, Fars newsinfo-icon agency reported.

According to eyewitnesses, the plane is probably buried under avalanche.

Moreover, rescue and search operation at the 4,500 meter altitude is becoming extremely difficult due to the steep slope of the site of the crash as well as the two-meter snow in the area. Meanwhile, more snowfall is expected in the coming hours.

At present, seven helicopters as well as nearly 100 rescue workers and mountain climbers, including Himalayan climbers, are continuing the search operation in the area.
