Sudan's civil aviation authority on Tuesday suspended all flights to and from Khartoum international airport until Saturday, the airport said.
The head of the civil aviation authority told Reuters that the suspension was due to the current events in the country.
Ibrahim Adlan said Sudanese airspace remains open to passing flights.
Protesters took to the streets on Tuesday after deadly clashes the previous day to demonstrate against the military takeover.
