MIAMI (AP) _ A Cuban-born U.S. citizen under arrest in her homeland went on state television there and described being recruited and trained by the CIA to spy in her native country.

Gladys Juana Oliva Garcia Hernandez, a 48-year-old Miami resident who was arrested in Cuba last month, said in the broadcast in Havana on Monday night that she was trained in Miami for spy work and went to Cuba last month to get her brother involved.

''I traveled to Cuba to recruit my brother,'' she said.

Her brother, Nestor Norberto Garcia Hernandez, who also has been arrested and who appeared on the same broadcast, said he agreed to work for his sister for the $500 he was promised by her.

The sister and brother were interviewed by a Cuban newscaster. The broadcast was monitored in Miami by Spanish-language radio station WQBA.

State Department spokesman Bruce Ammerman said U.S. officials had no comment.

The CIA, citing standard policy, has declined to confirm or deny whether Gladys Garcia had any links to the agency.

According to Cuba's Ministry of the Interior, she smuggled an electronic device into Cuba to allow her brother to transmit military and economic information to unspecified U.S. agencies.

Relatives in Miami said she had returned to Cuba in April to visit a sick brother. Although routine travel between the United States and Cuba has been restricted for years, Cuban exiles are allowed to return home to visit close relatives.

Gladys Garcia and her brother, an official in the Cuba's Ministry of Construction, have been charged with espionage, according to the Cuban government. The broadcast said they will be tried before a tribunal and could face up to life imprisonment.

According to U.S. Immigration and Naturalization officials, Gladys Garcia traveled from the United States to Cuba four or five times in recent years.

She lived in Dade County with her husband, Antonio Oliva, who arrived in the United States during the Mariel boatlift that brought 125,000 Cubans to the United States in 1980.
