The airline has suspended all flights from Morocco to Tunisia due to the ongoing civil war in the Middle East, its website reported.
The company said that the flight would be resumed when the government in Tunisia is able to provide an explanation for the suspension.
MoroccoAir’s suspension of flights to Egypt, Tunisia and Tunisia’s other major cities comes days after Egypt’s military overthrew Islamist President Mohamed Morsi.
The country has since imposed an economic embargo and has been under a state of emergency since the military takeover.
Morocco Airlines, which operates a fleet of Airbus A330s, was the second-largest airline in the world by revenue in 2016, with $2.2 billion in revenue.
Morocco has been struggling to find a way to attract more foreign customers amid its economic problems and has faced growing political pressure over its treatment of dissidents.
It also faces competition from Airbus Group SE, the world’s largest commercial airliner operator.
Morocco’s tourism sector is growing at a steady pace, with the country expecting to receive more than $1.6 billion in annual revenue from its air and sea transport, according to the Ministry of Tourism.
In October, the country announced that it would raise $1 billion for its economy and create 1,200 jobs by 2020, bringing its total budget for the year to $2 billion.
