Cuba has said it backs Venezuelan President Hugo Chavez in his country's spat with Colombia, media reports said.
At the end of a meeting between the Cuban and Venezuelan governments, Cuban President Raul Castro said his country supported the right of Venezuela to defend itself against threats and provocations, dpa reported.
Castro was reacting to comments by Chavez at the weekend that the United States and Colombia were preparing for an attack on Venezuela.
"We are fighting for peace and harmony between our kindred peoples," Castro said, according to reports in the Cuban media on Monday.
"Our talks will always have this aim. But in the event of any problem no one should have the slightest doubt on whose side Cuba would stand."
Venezuelan President Hugo Chavez broke off his country's relations with neighbouring Colombia last week over allegations that Colombian rebels were operating in Venezuela.
Colombia alleged at a meeting of the Organization of American States in Washington that the leftist Revolutionary Armed Forces of Colombia were operating from Venezuelan territory.
