Nanga Parbat, Illegal Bulgarian Ascent, 1993. In AAJ, 1994, pages 264-5, the report of a Bulgarian climb of Nanga Parbat was given. Apparently this was illegal. The Pakistani liaison officer with an Anglo-Polish expedition reported on his return from the mountains that this Bulgarian expedition had in fact been on the mountain without a liaison officer and without permission. Consequently, the five climbers are barred from climbing in Pakistan for four years.
