CARACAS (Reuters) – Venezuela’s bitterly divided political factions held competing commemorations of the country’s independence day on Friday, with President Nicolas Maduro calling for dialogue and opposition leader Juan Guaido decrying alleged human rights violations by Maduro’s “dictatorship.”

Speaking to a gathering of top military officials, Maduro reiterated his support for a negotiation process mediated by Norway between his socialist government and Guaido, the leader of the opposition-held National Assembly who argues Maduro’s 2018 re-election was a fraud.

“There is room for all of us within Venezuela,” Maduro said in a speech in Caracas, before calling for military exercises on July 24 to defend the South American country’s “seas, rivers and borders.”

“We must all give up something in order to reach an agreement,” he said.

Venezuela was plunged into a deep political crisis in January when Guaido invoked the constitution to assume a rival interim presidency, calling Maduro a usurper. He has been recognized as the rightful head of state by dozens of countries, including the United States and most South American neighbors.

But Maduro retains the recognition of Cuba, Russia and China, and remains in control of state functions and the armed forces. He calls Guaido a U.S.-backed puppet seeking to oust him in a coup.

Guaido held a separate independence day event, calling on supporters to march toward the headquarters of the military counterintelligence directorate, or DGCIM, where navy captain Rafael Acosta died last month after opposition leaders and family members said he was tortured in custody.

The march is the first major opposition gathering since a botched Guaido-led military uprising on April 30 and follow-up protests on May 1. The government responded to the failed attempt to oust Maduro with a crackdown on Guaido-aligned lawmakers and military members suspected of involvement.

This week, the United Nations human rights chief, former Chilean President Michelle Bachelet, published a report detailing alleged extrajudicial executions, torture, enforced disappearances and other rights violations by Venezuelan security forces in recent years.

“There is no longer any valid euphemism to characterize this regime, other than dictatorship,” Guaido told reporters earlier on Friday. “The systematic violation of human rights, the repression, the torture… it is clearly identified in the (UN)report.”

The Venezuelan government has called the report “selective” and said the UN sources lacked objectivity.

A new round of Norway-mediated talks expected for this week was called off after Acosta’s death. Opposition leaders frequently argue that Maduro’s government seeks to use dialogue to distract from its continued human rights violations.

In an apparent referral to Acosta before Maduro spoke, Commander Remigio Ceballos said the armed forces “regretted the events related to the loss of the retired naval official.” Without naming Acosta, he accused him of conspiring against the Venezuelan state, and said authorities were investigating the circumstances of his death.
