Brazil school shooting: At least 8 people killed

Eight people have been killed at a school in southern Brazil when two gunmen, ages 25 and 17, brandishing guns, knives and crossbows opened fire before taking their own lives.

Six students and two teachers were killed in the attack at the public school in Suzano, a suburb of Sao Paulo, according to the Associated Press. Officials said several people were receiving treatment for injuries.

The attackers appeared to be in their early to mid-20s and were not former students, AP reported.

The school was evacuated and security forces were investigating the possibility that explosives had been left at the building by the attackers.

Pupils gathered outside the school and recounted details of the attack, describing bodies lying in pools of blood.
