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

Sudan’s paramilitary 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.

The strikes hit Port Sudan’s airport, the main gateway for humanitarians and civilians entering or leaving Sudan, two years into the brutal civil war.
