Saudi Airlines has confirmed one of its jets in Manila was temporarily grounded after a false alarm of a hijacking attempt.
The pilot informed air traffic controllers the aircraft was “under threat” as it came into land in the Philippines on Tuesday but authorities later said there was no danger.
Saudia – also known as Saudi Arabian Airlines – attributed the incident to a “false alarm for hijacking” in a statement.
The Manila International Airport Authority (MIAA) said investigations were underway on Tuesday afternoon after the plane mistakenly sent a distress call.
Flight SV872, from Jeddah, was 20 miles from landing when the threat was reported, with controllers sending the Boeing 777 to land in an isolated area of Ninoy Aquino International Airport.
Officials said a hijack warning button was repeatedly pressed by the flight crew, sparking the mobilisation of security forces and isolation procedures.
Eddie Monreal, manager of the MIAA, said the distress call was sounded twice but the pilot later told air traffic controllers the signal was a mistake.
The plane landed at around 3pm local time (8am BST), with television footage showing emergency services at the scene.
Footage taken by passengers on board showed flight crew checking passengers’ documents amid rumours Indonesian nationals were using Philippine passports.
Its 410 passengers and 21 crew were later allowed to disembark from the aircraft, with some wearing the traditional white clothing signifying they had carried out the Hajj pilgrimage.
The incident came as millions of Muslims return from the annual journey to the Saudi Arabian cities of Mecca and Medina, which must be carried out once by every Muslim according to the five pillars of Islam.
In February, Philippine officials announced they had strengthened security for Saudi Arabia’s embassy in Manila and its national airline, with armed officers posted to guard the Saudia boarding zone and luggage bays because of a possible threat.
Security remains high in the Philippines amid an Islamist insurgency by the Isis-affiliated Abu Sayyaf group in the south and the ongoing “war on drugs” waged by President Rodrigo Duterte.
Since he took office in June, more than 3,000 suspected drug users and dealers have been killed by security forces and vigilantes, raising international alarm over judicial process.
Among them is Aurora Moynihan, the daughter of the late peer Lord Anthony Moynihan, who was found shot dead in Manila with a note reading: “Pusher to the celebrities, you are next”.
