A young Palestinian woman who was flown from Gaza to an Italian hospital in a severely emaciated state for treatment has died, AFP reports.

The 20-year-old, identified by Italian media reports as Marah Abu Zuhri, arrived in Pisa on an Italian government humanitarian flight overnight Wednesday-Thursday.

The University Hospital of Pisa said she had a “very complex clinical picture” and serious wasting, which is when a person has significant weight and muscle loss.

On Friday, after undergoing tests and starting treatment, she died after a sudden respiratory crisis and cardiac arrest, the hospital said.

The woman was flown to Italy with her mother on one of three Italian air force flights that arrived this week in Rome, Milan and Pisa, carrying a total of 31 patients and their companions.

The hospital did not elaborate on what caused her condition, but Italian news agencies reported that she was suffering from severe malnutrition.
