The strike at the vital economic hub comes amid weeks of anti-government demonstrations that began in December. Protesters have rallied across the country, including in Port Sudan, accusing President Omar al-Bashir's government of mismanaging the country's economy.
Workers are opposing Khartoum's decision to transfer control of the port's container terminal to a Philippine company, International Container Terminal Services Inc. (ICTSI).

The company said on its website that the tender process had been led by Sudan's state-run Sea Ports Corporation (SPC) and had attracted bids from several international operators.
