Tributes have been paid to a British teacher killed when an Air Algerie flight crashed in Mali on Thursday.
David Morgan, reportedly from Liverpool, was among the 116 people who died when the plane came down in a remote part of northern Mali.
PE teacher Andy Vasily posted on Twitter that Mr Morgan had previously worked at Nanjing International School in eastern China.
He wrote: " RIP Dave Morgan. Truly tragic. Prayers to his family and other victims."
Hanri de Swardt, a fellow teacher, from South Africa, wrote on Facebook: "Rest in peace Captain Dave Masher Morgan. Thanks for all the support and help in Lusaka. You will always be in my thoughts. God bless."
She added: "R emember the nice evening at Brentwood with all our last food before leaving Zambia."
Annabelle Mambwe, a teacher at Luanda International School, in Angola, wrote: "Just lost a teacher colleague in the Algiers disaster. Dave Morgan!! He was Denise's Maths teacher...such an easy-go-fella! These planes falling from the sky are getting to me!"
Another friend, Nicola Zulu, posted: "Was he with Evy? Oh my God, he was coming to Singapore to work and we had planned to meet up."
Yesterday David Cameron said he was "deeply saddened" by the death of the British national, adding: "Thoughts very much with friends and family."
A Foreign Office spokesman said: "It is with deep regret that the Foreign and Commonwealth Office confirms the death of a British man onboard Air Algerie flight AH 5017.
"We are providing consular support to his family at this tragic time, and we ask that the media respect the privacy of those grieving."
Mr Cameron has also written to French president Francois Hollande "to send sincere condolences for the loss of so many French citizens", Downing Street said.
The United Nations peacekeeping mission in Mali said its experts have found the second black box from the aircraft.
It was recovered from the wreckage in the Gossi region near the border with Burkina Faso
French soldiers secured the other black box yesterday.
Terrorism has not been ruled out as a cause of the crash, although officials have said that it is most likely to have been due to bad weather.
"There are, alas, no survivors," Mr Hollande told reporters following a crisis meeting with senior ministers. "I share the pain of families living through this terrible ordeal."
Nearly half of the passengers on board the flight were French, many due to head on to Europe after arriving in the Algerian capital Algiers from the Burkina Faso capital, Ouagadougou.
Mr Hollande declared that France will spare no efforts to find out what happened.
"There are hypotheses, notably weather-related, but we don't rule out anything because we want to know what happened," he said.
Interior minister Bernard Cazeneuve said: "Terrorist groups are in the zone. ... We know these groups are hostile to Western interests."
The MD-83 aircraft, owned by Spanish company Swiftair and leased by Algeria's flagship carrier, disappeared from radar less than an hour after it took off early on Thursday from Ouagadougou for Algiers.
The plane had requested permission to change course due to bad weather.
