Gulmira was Ho Yinsen's home town, who described it as a nice place.
After Tony Stark was kidnapped by the Ten Rings and subsequently escaped, he was confronted by journalist Christine Everhart during a party in Los Angeles, who showed Stark pictures of Stark Industries weapons in the hands of terrorist groups, including an arsenal of Jericho missiles in Gulmira.
Stark attacked the terrorists in Gulmira without harming the human shields and civilians that had been taken as hostages, leaving his former captor Abu Bakaar to the "mercies" of the residents of Gulmira. Stark located more arsenals containing fully-armed Jericho missiles and destroyed them.
Phil Coulson and Nick Fury, during their investigation surrounding the events of the Kidnapping of Tony Stark, immediately travelled to Gulmira to analyze Stark's role during his attack to the Ten Rings. They find footage recorded by the terrorist and intented to frighten civilians. The footage shows Stark in his armor defeating the terrorists.
