Nicaraguan President Daniel Ortega has accused the United States of backing opposition groups to subvert his leftist government.
In a speech in Managua, Mr. Ortega said U.S. officials were giving money and guidance to Nicaraguan opposition groups and media outlets.
Mr. Ortega led the leftist Sandanista National Liberation Front that toppled the U.S.-backed regime of Anastasio Somoza in 1979. During the 1980s, the Soviet-backed Sandanistas fought a civil war against U.S.-funded Contra rebels.
Mr. Ortega was Nicaragua's president from 1985 until 1990, when he was voted out of office. He was re-elected as president late last year.
Since taking office in January, President Ortega has strengthened relations with Iran, Venezuela and North Korea, countries critical of the United States.
