Airbus has confirmed that the aircraft which crashed at Tripoli today was an A330-200, although it has yet to identify the specific airframe.
The manufacturer says the aircraft had been arriving from Johannesburg.
Airbus says it will provide "full technical assistance", through the French Bureau d'Enquetes et d'Analyses, to the authorities investigating the accident.
Libya's Afriqiyah Airways was operating the aircraft. The accident is only the second loss of an A330 in airline service, following last year's Air France A330-200 crash over the South Atlantic.
Afriqiyah initially signed for up to six A330-200s in mid-2006, and started taking delivery of the three firmed aircraft last year.
