Mexico City, May 03: Mexico withdrew its ambassador from Cuba as relations between the former allies fell to an all-time low over Mexico's support for a UN rebuke of Cuba's human rights record. ''The President of the republic has decided to withdraw our ambassador in Havana and ask the Cuban government to pull its ambassador in Mexico out immediately,'' foreign Minister Luis Ernesto Derbez told a news conference yesterday.

Derbez said harsh criticism of Mexico by Cuban President Fidel Castro in a May day speech had contributed to the break down in relations. Interior Minister Santiago Creel also said two Cuban government officials in Mexico had been found ''carrying out activities incompatible with their status'', a term often used by governments to denote spying. Creel gave few other details about the Cubans.

Mexico angered Cuba last month by voting against it at a UN human rights body in Geneva. Bureau Report
