A samba school's use of blackface in a Carnival parade is sparking debate about depictions of race in Brazil, which has only begun in recent years to grapple with a fraught racial legacy.
Police say eight people have now died from the explosion of a gas canister at a Bolivian Carnival parade, and the toll of injured has risen to at least 40.
Police in Bolivia say six people were killed and dozens injured when a street vendor's gas canister exploded near the route of the Carnival in the city of Orura.
Hundreds of revelers are wrestling, tackling each other and throwing chunks of gunk while shaking it to samba and reggaeton at a Carnival beach party where clothes are optional but the mud is not.
Brazilians are letting off steam during the first full day of Carnival after a difficult year that included a lackluster economy, a spiraling corruption investigation and increasing political polarization.
