Drone strikes hit a fuel depot, airport and a hotel in Port Sudan, bringing violence to a city that had so far been spared in the devastating civil war.

The strikes are the first on the de-facto capital along the Red Sea. About a quarter of a million refugees have fled to the state where Port Sudan resides since the civil war erupted two years ago.

Explosions have been heard at the Port of Sudan, a critical lifeline and entry point for aid, as attacks on the city continued for a fourth day in the latest confrontation between Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Forces (RSF) in the country’s brutal two-year civil war.
