A drone attack has hit an area near the international airport in Sudan's capital, Khartoum, a day before it was set to resume domestic flights for the first time since war broke out in 2023.

Residents of the city reported hearing explosions in several districts early on Tuesday morning. Social media images - yet to be verified - appear to show a series of blasts.

There is no information on casualties or damage, and no-one has claimed responsibility for the attack.

On Monday, Sudan's Civil Aviation Authority had announced the airport would reopen on Wednesday, months after the army recaptured Khartoum from the Rapid Support Forces (RSF) and began repairing the heavily damaged facility.

This strike marks the third attack in the capital within a week, following strikes on two army bases in north-west Khartoum on consecutive days last week.

According to the Sudan Tribune, a security source reported that anti-aircraft defenses intercepted several drones after 04:00 local time (02:00 GMT).

The international airport was shut down shortly after fighting began between the army and RSF in April 2023 when the paramilitary group took control of it.

Port Sudan, located in the east, is currently the only functioning international airport in the country, though it has also faced drone threats.

Despite a relative calm after the army's recapture of Khartoum in March, the RSF has continued its assaults, accusing them of targeting civilian and military infrastructure from a distance.

The ongoing conflict has resulted in tens of thousands of deaths and has displaced millions. Initially sparked by a power struggle between the army and the RSF, the situation has deteriorated into what the UN refers to as the world's worst humanitarian crisis.
