Mykola Kyrylovych Lebed[a] (January 11, 1909 – July 18, 1998, also spelled Lebid;[b]; also known as Maksym Ruban, Marko, and Yevhen Skyrba) was a Ukrainian nationalist political activist and guerrilla fighter.

The follow-up report from the IWG's Richard Breitman and Norman J. W. Goda included a discussion of Lebed's relationship with the Central Intelligence Agency during the Cold War.: pref.

The report stated that as late as 1991 the CIA, for fear of compromising the operation and triggering outrage within the Ukrainian émigré community, shielded Lebed from prosecution for war crimes by preventing the United States Department of Justice's Office of Special Investigations from learning about his wartime connections to the Nazis.: 90–91.

After the assassination he attempted to flee through Gdańsk-Szczecin to Germany, but by order of Himmler was arrested by the Gestapo and handed over to the Polish authorities.

Lebed assumed control of Bandera's faction of the OUN in western Ukraine, which would come to dominate the Ukrainian Insurgent Army (UPA) until 1943.

[8] As leader of OUN-B, Lebed was responsible for the ethnic cleansing of around 100,000 Poles in Volhynia and Eastern Galicia, including giving orders to carry out the killings.

In 1956-91 he was a member of the board of the Ukrainian Society of Foreign Studies in Munich and Toronto, publishing committee "Chronicle of the UPA (1975).

Thanks to his collaboration with the CIA and their active shielding of him, Lebed was never tried for the war crimes he and his men had committed against Poles and Jews during WWII.
