Brazil has been celebrating carnival since Friday with big parties and parades, and there is more partying planned for the next few days. The scene turned to fear Sunday morning as a man opened fire after an argument in Paraty late Saturday night, Yahoo News reports via AFP.

Ten people were injured, five men and five women, in the city just west of Rio de Janeiro. The severity of their injuries is unknown.

The next two nights of carnival are expected to bring more than 70,000 people into the streets. The late-night partying and parades will not end until 4 a.m. local time.

Rio's violence usually calms down during the five days of carnival, but Saturday's shooting reminded Brazil of the violence problem. 

Police are stepping up their presence, and 15,000 are expected to be monitoring the festivities.

Sunday night will feature parades by Rio's elite samba schools. The 12 schools will be competing for this year's crown. 

Residents in Brazil hope to enjoy themselves the next two nights watching samba and percussionists during the late-night festivities.

"The excitement builds and builds. Then it's your school's turn to go and there you are, under the lights, the noise. It's an indescribable feeling," said Megumi Kudo, a solo dancer with the Salgueiro elite school. 

Carnival dates back to the 1700s, but samba schools did not begin forming until 1928.

All over Brazil residents will be celebrating and participating in street parties called "blocos." 

In 2011, the carinval in Rio attracted almost 5 million people, over 400,000 were foreigners, according to Folha De S. Paulo.

Party-goers in Rio and throughout Brazil hope for a peaceful conclusion of the carnival. With almost unending music and dancing, carnival will keep residents up all night Sunday and Monday.
