The Federal Government has put on hold the planned resumption of unity schools.
It has also stopped students from participating in the West African Senior School Certificate Examinations earlier scheduled for August 4 to September 5.
The Minister of Education, Adamu Adamu, broke the news to State House Correspondents at the end of the Federal Executive Council meeting presided over by President Muhammadu Buhari.
The minister said federal schools would remain closed until it is safe to reopen them.
He also urged state governments that have announced school resumption plans to rescind such.
Adamu stated that the West African Examinations Council cannot determine the resumption date of schools for Nigeria.
He said he would prefer that Nigerian students lose an academic year than to expose them to dangers.
