Who was on the Germanwings plane that crashed in the French Alps?

Opera singers, a group of exchange students and an architect were among the 150 people aboard the Germanwings plane that crashed in the French Alps on Tuesday.

Leaders in France and Spain have said they don’t believe there are any survivors.

Details are still emerging about the 144 passengers and six crew members on the Airbus A320, which was flying from Barcelona, Spain, to Dusseldorf, Germany, when it crashed.

Spain’s King Felipe VI said “high numbers of Spaniards, Germans and Turks” were on the aircraft. British Foreign Secretary Philip Hammond said it’s likely British nationals were on the plane, but officials have yet to confirm how many were aboard.

Weeping relatives arrived throughout the day at Barcelona’s airport, where a terminal was blocked off for them. Medics and psychologists were in private space to assist families.

Here’s what we know about the victims and their nationalities so far:

There were at least 67 Germans onboard, Germanwings CEO Thomas Winkelmann said. But he cautioned that figure could change as new information comes to light.

Sixteen students and two teachers from Haltern, Germany, were on the plane, Winkelmann said.

“The whole city is shocked and we can feel it everywhere,” Haltern Mayor Bodo Klimpel said at a news conference. “This is the worst, what happened … what you can imagine.”

The German students were returning home after spending a week at the Giola Institute, in the town of Llinars del Valles, near Barcelona, Spain’s El Pais newspaper reported.

Some of their relatives heard about the crash on the news. Some parents went to the airport while others rushed to the school, Joseph Koenig Gymnasium, Klimpel said.

The Gran Teatre del Liceu in Barcelona posted a statement on its Facebook page saying that two German opera singers who performed there this month in a production of “Siegfried,” Oleg Bryjak and Maria Radner, had perished in the crash.

Radner was returning to Germany with her husband and child, a spokesman for the production company said.

Bryjak, a bass baritone, had performed in the Deutsche Oper am Rhein ensemble since 1996, the Dusseldorf opera house said on Twitter.

Two Japanese nationals were booked for the flight, Japan’s Ministry of Foreign Affairs said.

Satoshi Nagata and Junichi Sato were scheduled to fly, but the ministry was still trying to confirm whether both men were actually on board the flight.

Nagata and Sato are residents of Dusseldorf, Germany.

Two Colombian nationals, María del Pilar Tejada and Luis Eduardo Medrano, lost their lives on the flight, Colombia’s Foreign Ministry said.

Medrano, 36, was an architect who had been working in Equatorial Guinea, according to the Fundacion Universitaria de Popayan, where he had studied.

Tejada, a 33-year-old economist, had been visiting her husband in Barcelona and was returning to Germany, where she was completing her doctorate at the University of Cologne, Colombia’s Caracol Radio reported.

At least two Australians were killed, Foreign Minister Julie Bishop said.

“Sadly, I can confirm that there were two Australian citizens onboard, a mother and her adult son from Victoria,” Bishop said. “It would not be appropriate to disclose further details of our citizens at this stage, due to the privacy considerations of the family.”

Officials are working to determine whether other Australian citizens or permanent residents were aboard the flight, she said.

“Our thoughts and prayers are with the families of the victims of this shocking tragedy,” Bishop said.

Two Argentines were aboard the plane, the state-run Telam news agency reported, citing consular officials.

The Dutch foreign ministry said there was at least one Dutch national on board.

Belgium’s foreign ministry said one Belgian national was on the plane.
