The United States is calling for a vote on a U.N. resolution urging "the peaceful restoration of democracy" in Venezuela, free and fair presidential elections, and unhindered delivery of humanitarian aid to all people in need.

The draft Security Council resolution was circulated to its 15 members Wednesday and obtained by The Associated Press. A council diplomat says it's expected to go to a vote on Thursday. The diplomat spoke on condition of anonymity ahead of an expected announcement.

The resolution is likely to be vetoed by Russia, which backs President Nicolas Maduro and the announced results of the May 20 presidential election that kept him in power.

The U.S. draft calls that election "neither free nor fair" and expresses "deep concern" at recent attempts to block aid deliveries.
