The fresh negotiations between the Academic Staff Union of Universities (ASUU) and Federal government reached a deadlock.
The meeting held at the headquarters of the national universities commission, Abuja, ended without any agreement.
The news has heightened anxiety of thousands of parents nationwide whose children have been at home since public universities shut down in February.
ASUU met with FG officials, including education minister, Mallam Adamu Adamu and members of the Nimi Briggs committee which renegotiated the 2009 agreement.
The meeting broke up after three hours when ASUU leaders walked out of the meeting.
ASUU president, Professor Emmanuel Osodeke told newsmen that the FG failed to make any fresh offer on the renegotiated 2009 agreement.
Sources close to the meeting said it broke up after federal government negotiators claimed there was no fund to implement the renegotiated agreement.
The striking lecturers were urged to return to classes, while their demands will be captured in the proposed 2023 appropriation bill.
