Explosions and fires rocked Sudan’s main port city and wartime capital Port Sudan on Tuesday, a witness said, part of a days-long drone assault that has torched the country’s biggest fuel depot, damaging the most important gateway for foreign aid.

Sudan's army said its anti-aircraft systems intercepted drones targeting the country’s largest naval base in the wartime capital Port Sudan on Wednesday.Explosions were heard in the city, though it was not immediately clear whether they were near the Flamingo base.

Sudan's paramilitary Rapid Support Forces unleashed drones on the Red Sea city of Port Sudan early Tuesday, hitting key targets there, including the airport, the port and a hotel, military officials said.
