A nationwide strike by state employees in Tunisia is taking place. BBC Africa reports that the most powerful union in Tunisia called for the stoppage to protest against the economic policies of President Kais Saied in the latest challenge to his rule. The UGTT union has urged its one million members to observe the strike across the country to protest against government plans for a wage freeze and cuts in subsidies, aimed at securing a $4bn loan from the International Monetary Fund.  Flights to and from Tunisia are being halted as a result of the industrial action.
