Internet access in South Sudan has been severely curtailed and phone services limited as the authorities scuttle a planned nationwide protest against the country's political leadership.

Internet monitoring site NetBlocks confirmed the disruption.

There's a heavy deployment of the military in the capital Juba.

The People's Coalition For Civil Action Rights, which called for the mass action, accuses President Salva Kiir and Vice-President Riek Machar of failing the country and is calling for their resignation.

Several activists accused of having links to the group have been arrested in recent days.
