The 71 people found dead in an abandoned refrigeration truck in Austria had been crammed in, five to a square meter (10 sq ft), police said on Sunday, as initial forensic tests indicated they had suffocated.
A baby girl and three other children were among the dead in the truck discovered on Thursday on a highway from the Hungarian border to Vienna, where it had been left 24 hours earlier.
The victims are thought to be refugees from Syria or possibly Afghanistan, part of a huge wave of migrants pushing through Europe that is sorely testing the European Union's ability to cope.
