Cuba has denied U.S. charges it deliberately cut off power to the United States' diplomatic office Havana.

In a statement carried by the Communist Party daily Granma, the government of President Fidel Castro said it categorically denies that there was any premeditated electricity cuts.  It blamed the loss of electricity on a faulty underground electric circuit.

Officials in Washington say electrical service to the mission was cut on June 5.  They say the Havana office has been using generators to supply power.
On Monday, a U.S. spokesman said no similar power problems had affected nearby buildings in downtown Havana near the U.S. office.

Cuban authorities have complained in the past about an illuminated sign at the U.S. office that displays messages about democracy and human rights.
