[3] The siege began on the mid-day of February 27, 1980, when seventeen guerrillas dressed in the warm-up clothes of joggers stormed the embassy compound, located in a suburb of Bogotá.

[5] The hostages included the Papal nuncio to Colombia, Angelo Acerbi, as well as the ambassadors from fourteen countries: Austria, Brazil, Costa Rica, the Dominican Republic, Egypt, El Salvador, Guatemala, Haiti, Israel, Mexico, Switzerland, the United States (Diego C. Asencio), Uruguay, and Venezuela.

On February 28, eighteen people, including the Costa Rican ambassador and fourteen other women, were freed by the hostage takers.

Early on March 17, the Uruguayan ambassador, Fernando Gomez Fyns, escaped from the embassy by jumping from a window and running to troops surrounding the compound.

The sixteen guerrillas left the embassy with the remaining twelve diplomatic hostages under the supervision of the Inter-American Human Rights Commission of the Organization of American States, and boarded a Cubana Airlines flight to Cuba.

After living in exile in Cuba, he eventually returned to Colombia in time to participate in the M-19's siege of his home town of Yumbo.
