Four students of Nassarawa State University were on Monday shot by security operatives during a protest over water scarcity in the institution.
The victims were among the hundreds of students who protested against the scarcity of electricity and water in the school.
During the protest, some soldiers invaded the school and started firing shots which left four students dead, a witness said.
Nassarawa State Police Command spokesperson, Michael Ada, confirmed the killing of the students but denied that they were shot by police officers.
He said the commissioner of police in the state was already at the scene.
