Gunmen with rifles have shot and killed one of Latin America's most famous folk singers, Facundo Cabral, causing outrage and grief across the region.
The Argentine singer and novelist was on his way to Guatemala's main airport when gunmen attacked his vehicle, hitting him with at least eight bullets.
Cabral's concert promoter Henry Farina was also wounded. The motive is not clear.
Cabral rose to fame in the early 1970s, one of a generation of singers who mixed political protest with literary lyrics and created deep bonds with an audience struggling through an era of revolution and repression across Latin America.
Guatemalan President Alvaro Colom said he had called his Argentine counterpart Cristina Fernandez to tell her of the shooting.
"It seemed to hit her hard and she asked me to keep her informed about how the investigation is developing," he said.
Colom said officials are interviewing survivors and witnesses and analysing images from video monitors in the area.
"Adios, amigo," tweeted Argentina's foreign minister, Hector Timerman, in a message that expressed "profound sadness" at the murder.
Cabral was riding in a truck that tried to flee the attackers by driving into a fire station. He was accompanied by a second vehicle carrying bodyguards, according to Guatemalan television.
