BERLIN (AP) -- Relatives of those killed in the crash of Germanwings flight 9525 have expressed anger after the airline announced that the return of victims' remains to Germany will be delayed.
About half of the 150 people killed on March 24 were German.
Lufthansa, Germanwings' parent company, had planned to bring the remains to Germany on June 9 and 10, allowing first funerals to take place June 12.
Elmar Giemulla, a lawyer representing several families, said Thursday that "anger and despair are growing" among the relatives, especially since no new date for the transfer has been set.
Germanwings spokesman Joachim Schoettes told The Associated Press the delay was caused by errors in the official death certificates, which rendered them invalid.
He says Germanwings hopes to resolve the issue "as soon as possible."
