Brazil school shooting leaves three dead

Three people have been killed and at least eight injured after a shooter opened fire at two schools in the Brazilian state of Espirito Santo, local police say.

The attacks happened about 10am on Friday in the small town of Aracruz, located 80km north of the state capital Vitoria.

Officials said an unidentified teenager in military attire had opened fire at two schools, one private and one public, and was still missing in the early afternoon.

Local police said they initially suspected the shooter was a student at one of the attacked schools but Espirito Santo's head of public security Marcio Celante told reporters that had not been confirmed.

The public security office said in a statement that police and rescue workers were taking care of those injured while continuing to search for the shooter.

One injured person had to be taken by helicopter to Serra, a larger city located about 60km south of Aracruz.

Espirito Santo Governor Renato Casagrande expressed his condolences to the victims' families and said that all local security forces had been engaged in the investigation.

President-elect Luiz Inacio Lula da Silva called it an "absurd tragedy".

"I extend my support to Governor Casagrande in investigating the case and comforting the communities surrounding the two affected schools," he said.

Lula is set to take office from President Jair Bolsonaro on January 1.
