Germanwings Alps plane crash: Search for remains intensifies

One week on from the Germanwings air crash, more resources are being provided to speed up the task of identifying the victims.

Officials say it could take four months before all victims are identified.

Earlier, prosecutors in Germany revealed that the co-pilot who crashed the plane had been treated for suicidal thoughts.

Andreas Lubitz, 27, is suspected of deliberately crashing the plane in the Alps, killing all 150 people on board.
