The Yobe State Government has shut down all boarding schools across the 17 Local Government Councils of the state.
The directive issued on Sunday is expected to take effect immediately.
Although there has been no official statement from the government or security agencies, one of the students told Channels Television that their teachers asked them to vacate the hostels and go home without giving them any reason.
Efforts to speak with the Commissioner for Basic and Secondary Education proved abortive as his phone was switched off.
However, a teacher who spoke to Channels Television said the decision was as the result of the increasing security threats across boarding schools in the country.
Students of the Senior Secondary School (SS3) have, however, been asked to stay behind.
