14.18 A fuller passenger list has been published by official Algerian news agency APS.
The list of passengers includes 51 French, 27 Burkina Faso nationals, eight Lebanese, six Algerians, five Canadians, four Germans, two Luxemburg nationals, one Swiss, one Belgium, one Egyptian, one Ukrainian, one Nigerian, one Cameroonian and one Malian, Burkina Faso Transport Minister Jean Bertin Ouedraogo reportedly said.
However, AFP is reporting that "at least 20" passengers were Lebanese.
The six crew members are Spanish, according to the Spanish pilots' union.
14.14 Fiona Govan reports from Madrid, Spain with the latest on the fate of AH5017, which was owned and staffed by the Spanish firm Swiftair:
Swiftair confirmed that the two pilots and four cabin crew are all Spanish, and said that contact had been lost with the plane 50 minutes after it took off from Burkina Faso this morning for Algiers.
The company said it was trying to establish the nationalities of those on board and were coordinating with the Spanish foreign ministry.
"At this moment we have emergency teams and company personnel working to establish what happened and as soon as we know more details we will release new statements," it said in a statement, according to Spanish websites.
According to Algeria media reserves of kerosene on the plane could have run out after an hour.
Spain's ministry for development and transport has called a crisis cabinet and is in touch with the company and authorities in Burkino Faso, Mali and Algeria.
Jose Manuel Margallo, Spain's foreign minister described the situation as "confusing" and is in touch with his Algerian counterpart Ramatane Lamama, as well as the Spanish prime minister.
Speaking on an office visit to Tunisia he said "the situation is very confused."
14.11 "I can confirm that it has crashed," the unnamed Algerian official who spoke to Reuters has said, declining to give details of where the plane was or what caused the accident.
13.57 An Algerian aviation official has told Reuters the plane has crashed.
No more details are currently available on the location, but Niger security sources say planes are flying over its border with Mali to search for the plane.
13.51 Swiftair, which owned and staffed the plane, has a relatively clean safety record, with five accidents since 1977, two of which caused a total of eight deaths, according to the Washington-based Flight Safety Foundation.
Air Algerie's last major accident was in 2003 when one of its planes crashed shortly after take-off from the southern city of Tamanrasset, killing 102 people. In February this year, 77 people died when an Algerian military transport plane crashed into a mountain in eastern Algeria.
13.45 French fighter jets based in the region have been dispatched to try to locate the missing plane, French army spokesman Gilles Jaron has said.
Quote Two Mirage 2000 jets based in Africa were dispatched to try to locate the Air Algerie plane that disappeared on Thursday.
They will search an area from its last known destination along its probable route.
13.42 David Millward explains why a Spanish-owned plane was being operated by an Algerian airline:
The aircraft was "wet leased" by Air Algerie from Swiftair [a Spanish airline company], which supplied both aircraft and crew. The practice of wet leasing is common in the industry. British Airways wet-leased a number of aircraft during the 2010 cabin crew dispute to maintain services.
13.30 There may have been as many as 80 French passengers on board AH5017, "airport sources" in Algeria have told EFE.
13.25 The Telegraph's David Millward, former transport editor, has been following events from the US:
David Soucie, a former investigator with the Federal Aviation Administration, has told CNN: “There is no reason to think there is anything mechanically wrong with the plane. There is some reason that it flew over restricted airspace.”
Speaking on CNN he adds that field could have been an issue when the pilot had to make a decision what route should be taken to avoid the storm.
13.19 Mike Pflanz reports for The Telegraph from Nairobi:
A European diplomat in Ouagadougou said that there was limited information available from the country's civil aviation authorities, but that he had been briefed that the aircraft left Burkina Faso airspace and had continued as planned over Malian territory.
There were reportedly many French citizens on the flight, which was likely to be routed over territory that was in the hands of al-Qaeda's affiliates in northern Mali until France intervened to push them out in 2013.
Despite this, the European diplomat said that there was no suggestion he had heard that the aircraft could have been specifically targeted by anti-French Islamist forces from the ground.
