Reino Gikman
Reino Gikman (allegedly born March 27, 1930, Ino, Terijoki, Russia) was the alias used by an undercover agent for the Soviet KGB who operated in Western Europe.
 Gikman used a Finnish passport and spent several years in Finland developing his illegal residence cover by posing as a Finn.
 The KGB was able to create fake Finnish citizenships by inserting fake births into the church records with the help of a priest of the Finnish Orthodox Church.
 Gikman's fake personality was however the result of the theft in 1952 of four registry books of church records from the Othodox repository in Kuopio.
 He received his first Finnish passport at a Finnish embassy, before ever entering Finland.
 He moved to Finland in 1966, and held various jobs in Helsinki in the 1960s, working among others in the "Suomalainen Kirjakauppa" bookstore.
 In 1968 he married a "Martta Nieminen", a holder of a Finnish passport and also a suspected Soviet spy.
 Their son was born in Düsseldorf in 1969.
Russians in Pakistan
Russians in Pakistan are a small expatriate community and consist entirely of students, employees, families and diplomats stationed inside the country.
 During the nine-year Soviet occupation of Afghanistan, Moscow had attempted to establish a commercial and industrial presence in Pakistan, by opening an Aeroflot office and setting up subsidiaries of steel and oil industries as well as a tractor factory.
 With only 56 Soviets in Pakistan in 1972, their numbers had suddenly jumped to 1,374 by 1980.
 In his book, the French political expert Roland Jacquard mentions that Pakistani authorities, who were already opposed to the Soviet presence in Afghanistan, became alarmed by the burgeoning increase of the population and entailed the Soviets to reduce their diplomatic presence in Islamabad by half.
 It has been alleged that during the time period, there was a strong presence of Soviet KGB agents in the country, who carried out spy work primarily from Peshawar and Islamabad in tandem with several hundred Afghan WAD agents, and monitored Pakistani aid to the Afghan mujahideen.
 According to Jacquard, one of the Soviet Union's objectives was to bring Pakistan under its sphere of influence and even when a sizeable number of Soviet diplomats were removed from operations in the country, there were approximately one-third who still worked for the KGB spy agency.
