Emirates Airline has suspended flights between Dubai and Khartoum due to the current political unrest in Sudan.
In a statement issued today, the airline said flights operated by FlyDubai to and from Khartoum and Port Sudan have also been cancelled.
"Until further notice, customers connecting onto Emirates flights to Khartoum and/or Flydubai flights to Khartoum or Port Sudan will not be accepted for travel at the origin," it added.
Affected passengers have been requested to contact their booking agent or Emirates reservations.
"We are monitoring the situation closely, and aim to give customers as much notice as possible if there are any further changes to our operations," the airline said.
