The Abia state government says “suspicious explosives” were discovered inside Union Primary School, Afaraukwu in northern Umuahia, LGA.
John Kalu, an information commissioner from Abija, said the school was shut down to protect students.
The commissioner said the explosive devices may have been relics of the Civil War era because of “evidence of corrosion”.
He said the state government is working with security agencies to discover the “source and nature” of the device.
The statement read: “The Abia State Government is currently working with relevant security agencies in the state to uncover the source and nature of the suspected explosive devices found at Union Primary School, Afaraukwu in northern Umuahia, LGA.
“Although the initial examination of the device shows evidence of corrosion leading to suspicion that the materials are relics from the Civil War era, we are waiting for the final official report of the EOD of the Nigerian police team that is currently investigating the incident.
“In the meantime, the necessary measures have been taken to protect students and school staff with security inspections that are underway while the school is temporarily closed.
“Governor Okezie Ikpeazu has ordered security agencies to launch proactive checks at other vulnerable locations out of caution.
“While we are thankful to God that there is no harm to life or property, we urge citizens and residents to continue to be vigilant and report suspicious situations to security agents.”
The revelation comes three days after the state government did so introduced curfew from 22:00 to 06:00 for Umuahia and Abu to prevent potential unrest.
The curfew was announced hours later the attackers attacked federal correctional facility and headquarters of the police command in the state of Imo.
