Military sources told EFE that the explosion on Saturday occurred due to a fire in an aviation fuel depot inside the Khartoum airport, controlled by the powerful paramilitary group Rapid Support Forces.
The sources and Khartoum residents said multiple RSF positions near the airfield were hit by heavy air and artillery bombardments launched by the regular Sudanese Army.
The military also carried out attacks on paramilitary camps in the central and eastern parts of the capital, as well as in the neighbouring city of Omdurman.
In response, the RSF launched mortar attacks and anti-aircraft artillery fire.
It is unknown if the attacks caused casualties.
On Friday, army spokesperson Nabil Abdallah said seven people died in "indiscriminate rebel attacks" in Omdurman.
These renewed attacks have followed the recent visits of Sudanese military leader Abdel Fattah al-Burhan to various strategic defence bases both in Khartoum and the northern part of the city, with the apparent aim of boosting the troop morale.
Among his visits, Al-Burhan toured the Wadi Sidna airbase on Thursday, located about 20km north of Khartoum.
This airbase's operational efficiency is deemed crucial for maintaining control over the capital. It serves as the launching point for fighter jets and drones used to target RSF positions.
Since April 15, the army and the powerful paramilitary forces have been embroiled in one of the most violent conflicts in Sudan's recent history.
The ongoing fighting has resulted in thousands of deaths and displacement of over 4.5 million people, with some forced to leave the country altogether.Â
