Relatives of Spanish victims of the Germanwings jet crash are retrieving the remains of their loved ones at Barcelona's airport after the airline sent them from France.

Lufthansa spokesman Martin Riecken says three families were at the airport Tuesday to oversee transport of their relatives' remains for funeral services after the remains of 29 victims were picked up a day earlier.

The remains went to Spain 12 weeks after the co-pilot of the Barcelona-Duesseldorf flight slammed the plane into the French Alps on March 24.

All 150 people aboard died. Among them were citizens of more than a dozen countries, including 72 Germans, 47 Spaniards and four with dual citizenship including Spanish.

Lufthansa has said all the remains should be sent to relatives by the end of the month.
