Lecturers at public universities in Nigeria have begun a two-week strike over pay and funding.
The industrial action comes just weeks after universities resumed for a new academic year.
Announcing the decision, the leader of the Academic Staff Union of Universities (Asuu), Professor Chris Piwuna, described the decision as "inevitable" due to what he said was government failures.
The government has urged lecturers to reconsider the strike, stressing that constructive dialogue remains the best way to resolve the crisis.
The government added that striking lecturers can expect not to be paid under the country's "No Work, No Pay" labour law.
