The pilots union says in a statement that all Middle East Airlines flights departing between 1200 and 1700 GMT will be delayed by two hours on Friday, Saturday and Sunday.

It was not immediately clear how many flights were affected by the protest.

The union launched the protest after the company laid off a veteran 60-year-old pilot who had been undergoing cancer treatment.

MEA has been trying to rebuild its image as one of the region’s top airlines following years of civil war and the global financial crisis.
