In the 1970s the FSLN began a campaign of kidnappings which led to national recognition of the group in the Nicaraguan media and solidification of the group as a force in opposition to the Somoza Regime. The Somoza Regime, which included the Nicaraguan National Guard, a force highly trained by the U.S. military, declared a state of siege, and proceeded to use torture, extra-judicial killings, intimidation and censorship of the press in order to combat the FSLN attacks. This led to international condemnation of the regime and in 1978 the administration of U.S. president Jimmy Carter cut off aid to the Somoza regime due to its human rights violations (Boland Amendment). In response, Somoza lifted the state of siege in order to continue receiving aid.
