Among the first countries on the territory of which the Soviet Republic began to conduct intelligence activities were the countries of the Muslim East. In 1923, a legal residency was established in Persia .
The activities of the residencies in Persia were directed by the 5th (Eastern) sector of the Foreign Department of the OGPU. At the same time, the INO was working on sending its agents to Persia.
As a historical source, the “Notes of the Chekist” by the Soviet resident in the Middle East G.S. Agabekov are of great importance. published in Russian  in Berlin in 1930. “Notes” in detail reflect the political situation in the Near and Middle East in 1923-1930, disclose the methods of work of the INO, characterize the direct organizers and participants of Soviet intelligence and counterintelligence activities in these regions and describe the operations they carried out. Agabekov personally took part in the preparation of the destruction of the Turkish adventurer Enver Pasha , who became one of the leaders of the Basmachism. Later Agabekov led the creation of OGPU agent networks in Afghanistan, Persia and Turkey.

Most of the Soviet residencies in Persia had their own “specialization”. The residency in Tehran, in addition to the general coordination of intelligence work, operated through its point in Kermanshah (not to be confused with the city of Kerman) in Iraq .
The Kermanshah residency worked against the white emigration and British authorities in Iraq. In Kermanshah, in the period from 1925 to 1928, under the cover of the post of secretary of the Soviet consulate, M.A.Allakhverdov showed himself as a talented intelligence officer , who in 1928 became a resident of the INO in Persia. Here he managed to organize penetration into White emigre circles, obtain information about German, Polish, Turkish and Japanese intelligence services working against the USSR from the territory of Persia, and also acquire valuable agents in the ruling circles of Persia.

Residency in Urmia  followed the activities of the British in the surrounding territories (in Urmia, intelligence activities were started by the future diplomatic agent and consul general in Yemen, A.B.Dubson ). In the tasks of the Tavriz  residency included the development of the Dashnaks , Musavatists  and white emigre circles. The Ardabil and Resht stations also worked not only against the Musavatists, but also against the white emigration. Bender Bushehr  the residency monitored the situation in the region inhabited by the tribes of southern Persia, which were a kind of lever in the hands of the British for pressure on the government of Persia, and also monitored the situation in the ports of the Persian Gulf.

The main task of the station in Mashhad was to work against British “colleagues”  and their agents from among local residents (in Mashhad in 1921, the future diplomatic agent and consul general in Yemen, K.A. ). In addition, she was engaged in identifying the connections of the British with the Basmachi gangs and the white emigration. In the late 1920s, Mashhad became the base of various White émigré organizations. It housed the branches of the “Russian All-Military Union”, “Turkestan Insurgent Committee”, “Uzbek Nationalist Movement”, which carried out subversive work against the USSR in close contact with the British special services.  Employees of the OGPU in Mashhad were also engaged in identifying British agents operating in the strip of the Soviet-Persian border and in Turkestan.

The Mashhad residency was particularly successful. Here in 1931-1936. A.M. Otroshchenko worked under the guise of an employee of the Soviet Consulate General  agent of the plenipotentiary representative of the OGPU in Central Asia, from 1934 he led the Mashhad station. He managed to obtain important information about the anti-Soviet activities of the White emigration, as well as the subversive activities of the British and Japanese intelligence services against the USSR. 
Based on the current situation in this region, the state security organs decided to infiltrate the British intelligence station in Mashhad, intercept the channels for the transfer of agents to Soviet territory and, ultimately, paralyze its hostile activities. As a result of a number of successful operations carried out in the 30s, including with the participation of the Soviet legal residency in Mashhad, where the Soviet consulate general functioned, accomplices of the British resident from among the Russian emigrants were detained, and the channels for supplying weapons to the Turkmen-Yomut tribe were blocked, who raised an uprising against the Soviet regime. 
The information obtained by Soviet intelligence was also used to carry out measures to combat smuggling. Thus, “our station in Tehran established that Iranian merchants, using the agreement with Soviet Russia on border trade, were exporting from the USSR a large amount of gold, precious stones, and foreign currency. <…>
The goods presented for inspection fully complied with the customs declarations. This went on for quite a long time, until V. Gridnev  did not pay attention to the fact that the goods are transported by the Iranians in new woolen bags, on which patches are sewn here and there. The inspection showed that it was under these patches that jewelry and considerable amounts of foreign currency were hidden. The channel of foreign exchange smuggling was cut off ” .
