RIO DE JANEIRO, Nov. 14 (Xinhua) -- At least six people were killed and another was wounded Friday in a shooting between alleged rival criminal gangs at a party hall in the Brazilian city of Rio de Janeiro, local authorities said.

The shooting took place in the northern Honorio Gurgel neighborhood, where alleged members of the criminal gang Comando Vermelho were holding a party, the police said.
