Qatar Airways rushed to cancel flights in the wake of today’s announcement that all Qatari-registered aircraft are banned from using the airspace of Saudi Arabia, Bahrain, the United Arab Emirates Egypt and the Maldives. The move came as these five states, plus Libya and Yemen, unexpectedly cut diplomatic relations with Qatar over allegations that its government has supported violent Islamist groups as well as siding with siding with Saudi Arabia’s arch rival Iran.

The Qatari flag carrier, including its private jet division Qatar Executive, will be forced to inefficiently re-route all flights to largely make use of nearby Iranian airspace to the east of the country that is connected to Saudi Arabia via a border that also has been closed. As of 3 a.m. local time on June 6 (midnight UTC), the operator was due to suspend all services to and from Saudi Arabia, the UAE and Bahrain. Flights to and from Egypt were due to end at 7 a.m. local time (4 a.m. UTC) on June 6, but no announcement has been made about services to and from the Maldives, Libya or Yemen.

Meanwhile, Saudi Arabian Airlines, Emirates Airlines, Etihad Airways, Air Arabia, FlyDubai and Gulf Air all announced they intend to suspend services to and from the Qatari capital Doha from Tuesday morning. Shipping traffic from Qatar also has been banned by the three Gulf states.

The Qatari government has condemned the severing of diplomatic relations, which also has resulted in its citizens being given 14 days notice to leave Saudi Arabia, the UAE and Bahrain. The move comes barely two weeks after U.S. President Donald Trump’s high-profile visit to Saudi Arabia, during which he called on Arab states to back the U.S. in a concerted campaign against terrorism. On June 4, a few hours before the diplomatic crisis unfolded, Trump praised the Saudi government for its efforts to fight alleged extremists.
