French hijacking of the FLN plane

On 22 October 1956, French forces hijacked a Moroccan civilian aircraft carrying leaders of the Algerian National Liberation Front (FLN) during the ongoing Algerian War. The Douglas DC-3 belonging to Royal Air Maroc was carrying Ahmed Ben Bella, Hocine Aït Ahmed, Mohamed Boudiaf, Mostefa Lacheraf, and Mohamed Khider. It was destined to leave from Palma de Mallorca for Tunis where the FLN leaders were to conference with Prime Minister Habib Bourguiba, but French forces intercepted the civilian aircraft over the Mediterranean Sea and redirected the flight to occupied Algiers, where the FLN leaders were arrested, derailing the planned conference in Tunis. It's considered one of the most important events in the Algerian War.

Context
The French protectorate over Morocco had ended months before, and King Muhammad V supported the FLN in the struggle for Algerian independence.

Details
On 21 October 1956, King Muhammad V of Morocco received a delegation of leaders of the Algerian National Liberation Front—Ahmed Ben Bella, Hocine Aït Ahmed, Mohamed Boudiaf, Mostefa Lacheraf, and Mohamed Khider—in Rabat. France disapproved of the meeting and Alain Savary, French Secretary of State for Tunisian and Moroccan Affairs under Guy Mollet, announced the suspension of aid to Morocco.

22 October at midday, with fake documents, the FLN delegation left Rabat for Tunis by way of Palma in Spain in order to avoid flying over Algeria to circumvent France. The Douglas DC-3 registered "F. OABV" belonged to Royal Air Maroc, an airline owned by the Moroccan state. After departing Palma, French forces over the Mediterranean redirected the Moroccan aircraft, ordering the French pilot to land it in Algiers where the FLN delegation was arrested.

Max Lejeune, Secretary of State for the Armed Forces, and Henri Lorillot and other French generals in Algiers were responsible for the operation, without interference from Robert Lacoste, French resident minister and governor general of Algiers at the time.

The hijacking and arrest of the FLN leadership derailed the planned conference in Tunis, to have been attended by the FLN delegation as well as Habib Bourguiba and Muhammad V, with the goal of establishing a North African Federation to promote the independence of Algeria and end the French-Algerian war.

Aftermath
King Muhammad V of Morocco was distraught and "feared for his own life."

Anti-French riots broke out targeting French people in and around Meknes, with dozens of casualties.

Legacy
Maati Monjib mentioned historians discussing the event as the first instance of a passenger aircraft hijacking in history, but it is not the case.
