Sudan's civil aviation authority on Tuesday suspended all flights to and from Khartoum's international airport until Saturday, October 30, its head told Reuters a day after the military seized power.
Ibrahim Adlan said the suspension was due to the current events in the country, adding that the airport will reopen at 2:00 am local time (0000 GMT) on Saturday.
Sudanese airspace remains open to passing flights, he added.
Protesters took to the streets on Tuesday to demonstrate against the military takeover after a day of deadly clashes.
