UNITED NATIONS (Reuters) - The United States has asked the United Nations Security Council to meet to discuss the situation in Venezuela on Tuesday, said diplomats after Venezuelan President Nicolas Maduro’s troops repelled foreign aid convoys at the weekend.

The United States has been pushing the 15-member council to formally call for free, fair and credible presidential elections in Venezuela with international observers, a move that prompted Russia to propose a rival draft resolution. It was unclear if or when either draft text could be put to a vote.

Moscow and Washington have been at loggerheads over a U.S.-led campaign for international recognition of Venezuelan opposition leader and head of the country’s elected National Assembly Juan Guaido over Maduro. Guaido last month declared himself interim head of state.
