Officials said the drone hit the airport and targeted an army base in the Port of Sudan on Tuesday.
The country's main fuel warehouse hit Monday, causing huge fires south of the eastern city until Sunday was considered a safe haven for hundreds of thousands of displaced people fleeing the Two Years' War.
A French agent reported a loud explosion at dawn Tuesday, smoke from coastal cities, one from the direction of the port and the other from the fuel warehouse in the south.
A drone attacked the "civilian area of Port Sudan Airport" and the military blamed the paramilitary rapid support force (RSF) for the first time, an airport official told AFP.
Sources added that all flights are rooted in major international entry ports of war-torn countries.
Another drone targeted a major army base in the city center, and witnesses reported an attack on a nearby hotel.
Both sites are close to the residence of Sudan Army chief Abdel Fattah al-Burhan, who fought with his former RSF commander Mohamed Hamdan Dagalo, his former deputy Mohamed Hamdan Dagalo.
The third drone hit a fuel warehouse near the densely populated central port, near the southern port of the city, where the United Nations, aid agencies and thousands of displaced people moved from Khartoum.
Witnesses in the north of the city reported air defense fires at the military base.
Since almost all Khartoums, including almost all Khartoums, have increasingly entered Army territory in March, the RSF has relied on drones more and more.
UN Secretary-General António Guterres heard an explosion early on Tuesday morning in Port Sudan.
Almost all humanitarian aid to Sudan has been declared famine, with nearly 25 million people suffering from a terrible sense of food insecurity reaching the Port of Sudan.
A traveler told AFP that the airport where Sudan Airlines resumed flights after a strike on Sunday, "the fire broke out in multiple buildings." Army sources said the strike also "targets fuel warehouses at the airport."
In recent weeks, the RSF has attacked civilian infrastructure in the Army-controlled Northeast region, causing widespread power outages for millions of people.
Since its inception, the war has killed thousands of people, uprooted 13 million, and caused the world's biggest crisis of hunger and displacement. It effectively divided the country into two parts, while the Army controls the center, the north and the east, while the RSF possesses almost the vast area of Darfur, and parts of its southern allies.
According to experts, RSF's reliance on drones has increased emphasis on its coverage and has hindered the Army's supply lines since the RSF lost Khartoum. The RSF used temporary and advanced drones, and the Army accused the United Arab Emirates of supply.
The International Court of Justice filed a case filed by Sudan against the UAE on Monday, accusing it of accusing it of accusing it of accomplices in genocide by supporting the RSF.
The Sudanese Foreign Ministry said on Tuesday that the ruling “respect” the ruling, which is based on the lack of jurisdiction over the 2005 "reservation" of the 2005 United Nations Convention on Genocide.
