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.

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.

Explosions and fires rocked Sudan's wartime capital Port Sudan on Tuesday, a witness said, part of a days-long drone assault that has torched the country's biggest fuel depots and damaged its primary gateway for humanitarian aid.
