Sudan has recalled its ambassador to Ethiopia on Tuesday after accusing Ethiopia of a series of drone attacks that hit its capital's international airport.

Sudan's Foreign Minister Mohi El-Din Salem said in a statement that the ambassador would be recalled for consultations and that his country is "ready to enter into an open confrontation with Ethiopia."

The drones that attacked Sudanese facilities on Monday were launched from Ethiopia's Bahir Dar Airport, he said.

Sudan has the legal right to respond to the "aggression" in the manner it deems appropriate, he added. "We do not seek to initiate aggression against any country, but whoever attacks us will be responded to."

For his part, Asim Awad Abdelwahab, spokesperson of the Sudanese Armed Forces, said in a statement that the armed forces "will respond twice as hard," noting that the army has "confirmed information regarding Ethiopia's participation in the aggression against Sudan."

"Our armed forces are fully prepared to deal with any threat in a manner that preserves the dignity, sovereignty and security of the nation," he said.

The statements come after drone attacks targeted Khartoum International Airport and military sites in the capital on Monday, triggering explosions and sending plumes of smoke from various locations. No casualties or damage were reported, according to the press office of Sudan's Ministry of Culture and Information.

The attacks also targeted the vicinity of the Signal Corps in Bahri, north of the capital, as well as the Al-Markhiyat camp north of Omdurman, with no confirmed information on the extent of losses.
