Gunmen opened fire at a crowded nightclub in Brazil on Saturday, killing at least 14 people.
At least another six people were injured in the attack that took place in the northeastern Brazil city of Fortaleza, authorities said.
They are being treated at local hospitals in Fortaleza, said Andre Costa, who heads the Ceara state security secretariat, which oversees police forces.
He told journalists that a motive was not yet known, but authorities were investigating whether the killings were part of an ongoing fight between two drug gangs.
No suspects are in custody.
Eyewitnesses told the Globo TV network that three cars full of armed men arrived at the dance club around 12:30 a.m. and fired rounds into the front of the building for at least a half-hour before fleeing.
Brazil routinely has more homicides than any other nation, according to an annual United Nations compilation of violence. In recent years, homicides have increased significantly more in the country’s northeast area than in the rest of the nation.
