A leader of a failed two-month strike to oust President Hugo Chavez was granted asylum by Costa Rica on Friday, the Costa Rican foreign ministry said.
Labor union leader Carlos Ortega, who faces treason charges, entered the embassy earlier Friday and was granted diplomatic asylum, Costa Rican Ambassador Ricardo Lizano said.
"For humanitarian reasons ... [Costa Rica] decided to grant asylum and it has communicated as much to the Venezuelan government," the Costa Rican foreign ministry said in a statement.
The statement said Ortega cited fear for his personal security when he requested asylum. He had been in hiding since Feb. 20, after a judge issued a warrant for his arrest for treason, rebellion and incitement.
Costa Rica is evaluating whether to grant Ortega territorial asylum, which would allow him to live in the country, Lizano said.
Venezuela would grant safe conduct to Ortega if he is granted territorial asylum, Interior Minister Lucas Rincon said.
Chavez said on state television that Ortega's asylum request "demonstrated the criminal character" of the strike leaders. "They are sabotagers and terrorists who greatly harmed the country," he said.
At the same time, hundreds of flag-waving supporters gathered around the Costa Rican embassy in eastern Caracas, chanting, "Ortega, friend, the people are with you!"
Ortega, head of the country's largest labor union, helped orchestrate a general strike to demand early elections or Chavez's resignation. The strike, which petered out last month, paralyzed Venezuela's lifeblood oil industry and cost the country $6 billion, according to government estimates.
Last month, authorities arrested strike leader Carlos Fernandez, president of Venezuela's largest business association. He is under house arrest pending trial on charges of rebellion and instigation. A judge struck down a treason charge.
Arrest warrants also are out for seven executives of the state-oil monopoly, Petroleos de Venezuela S.A. The seven are in hiding.
Opposition leaders have denounced the warrants as political persecution. Chavez says strike leaders must be imprisoned for at least 20 years for inflicting suffering on the population.
Ortega is the third Chavez opponent to seek asylum abroad.
Last year, Colombia granted asylum to business leader Pedro Carmona, the figurehead in an April coup that ousted Chavez for two days. El Salvador granted asylum to another alleged coup leader, Vice Admiral Carlos Molina Tamayo.
Chavez opponents accuse him of steering Venezuela's economy into recession with leftist policies. They also say he has accumulated too much power under the guise of a "social revolution" to help the poor.
Chavez says his foes resent his efforts to end social inequality and his success in wresting power from two corrupt traditional parties that ruled Venezuela for 40 years, until his 1998 election.
Chavez fired 15,000 workers from the oil monopoly -- almost half the work force -- for participating in the stoppage. He has threatened to close four private television stations that gave supportive coverage to the strike.
