(CNN) -- A float in Rio de Janeiro's Carnival parade partially collapsed with dancers on board, injuring several people early Tuesday.
Rio de Janeiro's Municipal Health Secretariat said at least 11 were injured. Nine people were transported to hospitals, Brazilian media reported.
The two-tier float was part of the lineup of the Unidos de Tijuca samba school's parade. This year's theme was inspired by American jazz culture.
This is the second accident registered during Rio de Janeiro's two-day carnival parade. On Sunday, at least 20 people were injured when a float from another samba school crashed into a fence.
