Venezuela s government has halted lines of communication established by a top U.S. diplomat to protest what it says has been U.S. interference in the country s internal affairs ahead of an election set next month to replace the late President Hugo Chavez.

Foreign Minister Elias Jaua said in a news conference Wednesday that U.S. Assistant Secretary of State for Western Hemisphere Affairs Roberta Jacobson had violated Venezuela s sovereignty despite reaching out to the South American country s government before Chavez s March 5 death.He accused Jacobson of supporting opposition candidate Henrique Capriles, although he didn t provide any evidence.We want normal relations with the United States based on mutual respect," Jaua said.

He said the government had formally "suspended any contact and any communication that had been established with the call of Mrs. Jacobson in the month of November." He emphasized, however, that diplomatic and consular relations would remain between the two countries.The U.S. Embassy in Caracas had not responded to a request for comment by Wednesday afternoon.

Venezuela s government expelled two U.S. military attaches this month for allegedly talking to members of the country s armed forces. Washington responded by ejecting two Venezuelan diplomats, who were honored by Jaua Wednesday.The two countries haven t had ambassadors posted in each other s capitals since 2010.Ahead of an April 14 presidential vote, Venezuelan officials have escalated their rhetoric against the U.S., with acting leader and government candidate Nicolas Maduro even accusing the U.S. of infecting Chavez with the cancer that killed him.

And even as Maduro has said U.S. officials are backing Capriles candidacy, he has accused two former U.S. assistant secretaries of state of plotting to kill Capriles in the hopes of fomenting a coup. The U.S. State Department has rejected that accusation while calling for free and fair elections.On Wednesday, Jaua accused the former U.S. diplomats of seeking Central American mercenaries to carry out the supposed assassination plot."Hopefully there will be a rectification and the meddling of the United States will cease," Jaua said.
